High-speed winds transfer more energy to the ocean’s surface, creating bigger waves.



Question 10 options:
True
False

Answers

Answer:

I think that would be true. The faster the wind, the longer it blows, or the farther it can blow uninterrupted, the bigger the waves. Therefore, a wave's size depends on wind speed, wind duration, and the area over which the wind is blowing

Answer: True.

Explanation: Yes, waves get energy from the wind through friction, so you see those waves get bigger each time. The longer the winds blows, the more friction, and energy it's getting, meaning better, and deadly waves. The wind can sometimes cause tsunamis if the its blowing too hard.

What will a balloon do to a cloth if its negatively charged

Answers

Answer:

This involves negatively charged particles (electrons) jumping to positively charged objects. When you rub the balloons against the fabric they become negatively charged. They take some of the electrons from the fabric and leave them positively charged.

Explanation:

Negative charges attract to positive charges. If a balloon is not rubbed with the wool cloth, it has an equal amount of negative to positive charges, so it will attract to a rubbed balloon. When both balloons are rubbed with the wool cloth, the both receive negative charges, so they will repel each other.

find out the number of moles and use the molar ratio (numbers in front of formulas (in this case they are all 1) to determine how many moles of each product you are going to get theoretically

n=m/M is the equation to use to get moles here

30.8 gm/32.04 g/mol=0.9612 moles of the methanol and also of the formaldehyde so

0.9612 moles of the formaldehyde x molar mass (M) 30.73 g/mol= 29.54 gm which is the theoretical yield you already have the actual yield of 24.7 gm

then divide the actual by the theoretical to get the % yield which is 83.6%

Answers

Answer:

a heterogeneous mixture

Explanation:

I can see all of the different parts of the frozen yogurt, and if I were to pick up a gummy bear, it would come out. Thus, it is not fully/completely mixed with the other components.

It is a heterogenous mixture.

What is the difference between Homogeneous  and Heterogeneous Mixtures ?

A type of mixtures where all the components are mixed uniformly called as homogeneous mixture.

Here the Particles are distributed in an uniform way, called as solution. Example rainwater, vinegar.

It consist of one phase, It can’t be separated out physically  

In heterogenous mixture, all the components are completely and equally mixed, particles can be seen under a microscope.

Here the Particles are distributed non-uniform way, Example: seawater, pizza, etc.

It can be in two or more phases and separated out physically

Answers

Answer:

2.3 X 10^24 atoms CO2

Explanation:

Answer:

2.30 x10²⁴ molecules CO2

Explanation:

Convert mass of CO2 to moles

Convert moles of CO2 to molecules using Avogadro's number.

168.2 g CO2 x 1 mole CO2 / 44 g CO2 x 6.022 x10²³ molecules CO2 / 1 mole CO2

= 2.30 x10²⁴ molecules CO2

If 23.2 g of a given gas occupies a volume of 93.2 L at a particular temperature and pressure, what
mass of the gas occupies a volume of 10.4 L under the same conditions?

Answers

Answer:

2.59g

Explanation:

Using Avagadro's law equation as follows:

V1/n1 = V2/n2

Where;

V1 = initial volume (litres)

V2 = final volume (litres)

n1 = first amount of gas in grams

n2 = second amount of gas in grams

According to the information provided in this question, v1 = 93.2L, v2 = 10.4L, n1 = 23.2 g, n2 = ?

Using V1/n1 = V2/n2

93.2/23.2 = 10.4/n2

Cross multiply

93.2 × n2 = 23.2 × 10.4

93.2n2 = 241.28

n2 = 241.28/93.2

n2 = 2.588

n2 = 2.59g

The mass of the gas is 2.59g that occupies a volume of 10.4 L under the same conditions.

Avogadro's law equation:

V₁/n₁ = V₂/n₂

Where

V₁ = initial volume (litres)

V₂ = final volume (litres)

n₁ = first amount of gas in grams

n₂ = second amount of gas in grams

Given:

V₁ = 93.2L,

V₂ = 10.4L,

n₁ = 23.2 g,

To find:

n₂ = ?

On substituting the values:

93.2/23.2 = 10.4/n₂

93.2 * n₂ = 23.2 * 10.4

93.2* n₂ = 241.28

n₂ = 241.28/93.2

n₂ = 2.588

n₂ = 2.59g

Thus, the mass of the gas is 2.59g.

To find the symbol of the element, you have to use the periodic table.  

The mass number is the number of protons and neutrons in the atom.  

The atomic number is the number of protons in the atom.

You can find the number of protons from the periodic table.

You can find the neutrons by subtracting the mass number by the number of protons in the atom.

Unless you have an ion, you will have the same amount of electrons as you do protons.

To write in nuclear notation, you write the chemical symbol with the mass number and atomic number shown in the attachment.  It is preferable to have the mass number and atomic number directly above each other.

Given the following reaction: 2N2O5=2N2O4+O2, if the rate of oxygen production is 0.15M/min, determine:
a. The rate that N2O5 is consumed
b. The rate that N2O4 is produced

Answers

Answer:

a. [tex]r_{N_2O_5}=-0.075M/min[/tex]

b. [tex]r_{N_2O_4}=0.075M/min[/tex]

Explanation:

Hello.

In this case, according to the balanced chemical reaction, we can write the law of rate proportions:

[tex]\frac{r_{N_2O_5}}{-2} =\frac{r_{N_2O_4}}{2} =\frac{r_{O_2}}{1}[/tex]

Thus, we proceed as follows:

a. Since the rate of oxygen production is 0.15 M/min, we can make the following setup:

[tex]\frac{r_{N_2O_5}}{-2} =\frac{r_{O_2}}{1}\\\\r_{N_2O_5}=\frac{r_{O_2}}{-2} =\frac{0.15M/min}{-2}\\\\ r_{N_2O_5}=-0.075M/min[/tex]

b. Since the rate of oxygen production is 0.15 M/min, we can make the following setup:

[tex]\frac{r_{N_2O_4}}{2} =\frac{r_{O_2}}{1}\\\\r_{N_2O_4}=\frac{r_{O_2}}{2} =\frac{0.15M/min}{2}\\\\ r_{N_2O_4}=0.075M/min[/tex]

Answer:

shift to restore equilibrium

Explanation:

Le Châtelier's Principle states that when a stress is applied to a system at equilibrium, the system will respond by shifting in the direction (either towards the products or reactants side) that opposes/ minimizes the effect of the stress.

Note that although the system tries to restore equilibrium, this equilibrium is a new equilibrium.

Equilibrium is the state of a reversible reaction when:

• two opposing reactions occur at the same rate;

• the concentrations of reactants and products are constant

The modern languages of the first are spoken only on and around the Cameroon grasslands, while all the other Bantu languages belong to the second. Therefore, in practice Bantu usually refers to Narrow Bantu. Narrow proto-Bantu emerged from Wide Bantu in the Sanaga valley just south of the grasslands of western Cameroon. Until recent times, this huge expansion was believed to have been brought about by a single vast human migration.It proved however to be exceedingly difficult to establish the genetic subdivisions of Narrow Bantu that such a migration would have produced, mainly because the daughter languages have borrowed so much from each other and otherwise changed over the past millennia that much of the evidence for their exact genetic relationships has been erased.
