Answer:

Methane (CH4),Carbondioxide green house gases are carbon compounds

Carbon dioxide (CO2) and methane (CH4) are two powerful greenhouse gases produced by the carbon cycle.

Answer:

a) [tex]Q_w=5941.3J[/tex]

b) [tex]C_{Cu}=0.378\frac{J}{g\°C}[/tex]

Explanation:

Hello there!

In this case, when a hot substance is mixed with a cold one, we can evidence how the hot one is able to heat up the cold one as it cools down. Thus, the net heat flow for this problem can be set up as shown below:

[tex]Q_{Cu}+Q_{w}=0[/tex]

Whereas the heats can be written in terms of mass, specific heat and temperatures:

[tex]m_{Cu}C_{Cu}(T_F-T_{Cu})+m_{w}C_{w}(T_F-T_{w})=0[/tex]

Thus, we proceed as follows:

a. Here we compute Qw:

[tex]Q_w=1,000g*4.184\frac{J}{g\°C}(21.42\°C-20\°C) \\\\Q_w=5941.3J[/tex]

b. Now, since this heat is equal to the negative of the heat contribution of copper (as it cools down), we can compute the specific heat of copper as shown down below:

[tex]C_{Cu}=\frac{-5941.3J}{200g(21.42\°C-100\°C)} \\\\C_{Cu}=0.378\frac{J}{g\°C}[/tex]

Best regards!

Answer:liquid

Explanation:

The particles in a liquid usually are still touching but there are some spaces between them. The gas particles have big distances between them.

Given values are:

As we know the relation,

→ [tex]Fs = K\times x[/tex]

or,

→   [tex]x = \frac{Fs}{k}[/tex]

By putting the values, we get

        [tex]= \frac{8.7}{190}[/tex]

        [tex]= 4.6\times 10^{-2} \ m[/tex]

Thus the response above is right.

Answer:

the electron of one atom and the nucleus of another

Explanation:

A photon is a quantum of EM radiation. Its energy is given by E = hf and is related to the frequency f and wavelength λ of the radiation by

E=hf=hcλ(energy of a photon)E=hf=hcλ(energy of a photon),

where E is the energy of a single photon and c is the speed of light. When working with small systems, energy in eV is often useful. Note that Planck’s constant in these units is h = 4.14 × 10−15 eV · s.

Since many wavelengths are stated in nanometers (nm), it is also useful to know that hc = 1240 eV · nm.

These will make many calculations a little easier.

All EM radiation is composed of photons. Figure 1 shows various divisions of the EM spectrum plotted against wavelength, frequency, and photon energy. Previously in this book, photon characteristics were alluded to in the discussion of some of the characteristics of UV, x rays, and γ rays, the first of which start with frequencies just above violet in the visible spectrum. It was noted that these types of EM radiation have characteristics much different than visible light. We can now see that such properties arise because photon energy is larger at high frequencies.

Answer:

potassium (K) and fluorine (F)

Explanation:

Potassium is an alkali metal just like sodium and fluorine is a halogen just like chlorine. A metal and nonmetal will often join to form an ionic compound.

Aluminum, if it was going to bond to itself, would be a metallic bond.

Sulfur and oxygen are both nonmetals and would form a covalent bond.

Calcium would not bond with neon as neon is a noble gas.

Answer:

A) potassium (K) and fluorine (F)

Answer:

11.8g of CaCl₂ would be required

Explanation:

To solve this question we need to find the moles of AgNO₃ in the solution. Thus, and using the chemical reaction we can find the moles of CaCl₂ required for a complete reaction and its mass as follows:

Moles AgNO₃:

420mL = 0.420L * (0.506mol / L) = 0.213 moles AgNO₃

Moles CaCl₂:

Based on the chemical reaction, 2 moles of AgNO₃ react per mole of CaCl₂.

The moles of CaCl₂ that will react are:

0.213 moles AgNO₃ * (1mol CaCl₂ / 2 mol AgNO₃) = 0.106 moles CaCl₂

Mass CaCl₂ -Molar mass: 110.98g/mol-

0.106 moles CaCl₂ * (110.98g / mol) =

Answer:

freezing

Explanation:

When a solid reaches the temperature of its melting point, it can become a liquid. For water, the temperature needs to be a little over zero degrees Celsius (0oC) for you to melt. ... The reverse of the melting process is called freezing. Liquid water freezes and becomes solid ice when the molecules lose energy.

Answer:

Explanation:

Metal elements form positively charged ions called cations because they are located on the left side of the periodic table These elements all have valence electrons in an s orbital. These electrons are relatively easy for the atom to lose to achieve a stable octet of electrons in its outermost energy shell.
