Which is an example of current electricity?
O A. Positively charged particles are attracted to negatively charged
particles.
O B. Negative and positive electric charges build up in different regions
of a cloud.
O C. Electrons flow from an outlet into a toaster, causing it to heat a
slice of bread.
O D. A person rubs a shoe on a rug, causing extra electrons to be
transferred to the shoe.
Answer:
C. Electrons flow from an outlet into a toaster, causing it to heat a
slice of bread.
Explanation:
Current produces a heating effect. Current may be used to produce a heating effect in appliances such as the electric pressing iron, toaster, oven etc.
When electrons flow from an outlet into a toaster and the current thus obtained heats a slice of bread, current is said to flow from the outlet into the toaster.
Let us remember that current refers to the flow of electrons in a circuit.
Why does powdered calcium carbonate react faster with hydrochloric acid than calcium carbonate chips?
Answer:
Exposed surface area
Explanation:
The powdered calcium carbonate will react faster with hydrochloric acid than calcium carbonate chips due to the exposed surface area.
Powdered calcium carbonate has a larger surface area compared to the chips. And, the larger the surface area exposed on a body, the faster the reaction it will undergo.
For the same masses of a solid substance, the smaller the particle size of each form, the larger the surface area exposed to reaction.
The surface area exposed proportionally affects the rate of reaction.

Which property of gases is explained by the process of diffusion?
A.
their ability to compress under high temperature
B.
their ability to expand under low temperature
C.
their ability to expand under pressure
D
their ability to fill the available volume of a container
Answer:
The appropriate alternative is "Option D".
Explanation:
Diffusion would be a random or physical phenomenon that corresponds to that same transfer budget of molecules from some kind of highly concentrated area to something like a lower one. The substance which diffuses may be strong, liquids, and gaseous. Correspondingly, the framework where certain diffusion happens can however be amongst the three aspects of sustainability.All those other options aren't relevant to the situation in question. So the above alternative becomes the right one.

(GIVING BRAINLIEST!!!)What is the correct formula for the ionic compound that forms when oppositely- charged ions of calcium and carbonate attract?
(ANSWERS ARE IN THE IMAGE)
Answer:
CaCO₃
Explanation:
Calcium ion is written as Ca²⁺
Carbonate ion is written as CO₃²¯
During bonding, the +2 ions from the calcium and the –2 ions from the carbonate will cancel out given a net charge of zero as shown below:
Ca²⁺ + CO₃²¯ —> CaCO₃
Thus, the correct formula for the ionic compound that forms when oppositely charged ions of calcium and carbonate attract is CaCO₃.

Describe Photosynthesis and explain the number of atoms and molecules that are used in a reaction.
Answer:
Photosynthesis reactions are naturally occurring processes that take place in all green plants and most algae. During this process the plant uses light energy, carbon dioxide, and water to make food and then releases oxygen which all living organisms require to the atmosphere.During the process of photosynthesis, cells use carbon dioxide and energy from the Sun to make sugar molecules and oxygen. These sugar molecules are the basis for more complex molecules made by the photosynthetic cell, such as glucose
Explanation:
1. A dry food product is contained in a 1 cm x 4 cm x 3 cm box using a polymer film to protect the oxygen sensitivity of the product. The concentration gradient across the film is defined by the oxygen concentration in air (0.01164 kg/m3) and 0.244 kg/m3 within the package. The oxygen diffusivity for the polymer film is 3 x 10-16 m2/s. Estimate a- the allowable flux of oxygen into the package (in kg O2/s), and b- the film thickness needed, to ensure a product shelf life of 10 months. The shelf life of the product is established as the time when oxidation reactions within the product have used 0.5 mol of oxygen.

calculate h30+ for a 8.86*10^3 hbr solution
[H₃O⁺] = 8.86 x 10³ M
Further explanationThe dissociation of water :
H₂O(l)⇒H⁺+OH⁻
Hydrogen ions H⁺ bond with H₂O to form H₃O⁺ ions(hydronium ion)
When acid(Hbr acid) is in the presence of water(dissociates), the H⁺ ions bond with water molecules to form hydronium, the reaction :
HBr(aq)+H₂O→H₃O+(aq)+Br−(aq
So Ionization of HBr :
[tex]\tt HBr\rightarrow H_3O^++Br^-[/tex]
[HBr]= 8.86 x 10³,
From equation ratio [H₃O⁺] : HBr = 1 : 1, so
[tex]\tt [H_3O^+]=8.86\times 10^3[/tex]

The concentration in parts per million (ppm) is
a 1.3x10^6
b 1.3x10^3
c 1.3x10^-3
I dont understand how to do this question. Help would be much appreciated!
Answer:
1300 ppm
Explanation:
for ppm, calculate fractional ration =(part/total) and multiply by 1 x 10⁶ => ppm
for ppb, calculate fractional ration =(part/total) and multiply by 1 x 10⁹ => ppb
Parts Per Million (ppm)
Given 1.36g in 1Kg (=1000g) => fractional ratio = (1.3g/1000g)(10⁶) = 1300 ppm
Parts Per Billion (ppb)
or if ppb is needed do the same calculation but multiply by 10⁹ ... That is,
Given 1.36g in 1Kg (=1000g) => fractional ratio = (1.3/1000g)(10⁹) = 1300000 ppb = 1.3 x 10⁶ ppb
Parts per Hundred (pph) is the same as percent (%) ... Calculate fractional ratio and then multiply by 100%
Given 1.36g in 1Kg (=1000g) => fractional ratio = (1.3g/1000g)(100%) = 0.13%
Why would Magnesium Phosphate (Mg3(PO4)2) not make an aqueous solution?
Please help!
Answer:
[tex]\boxed {\boxed {\sf Almost \ all \ phosphates \ are \ insoluble}}[/tex]
Explanation:
For magnesium phosphate to make an aqueous solution, it must be soluble in water.
Let's check the solubility rules. There are many different lists and versions, but it should mention a rule about phosphates.
All phosphates are insoluble except Na₃PO4 (sodium phosphate), K₃PO4 (potassium phosphate), and H₁₂N₃PO₄ (ammonium phosphate).Magnesium phosphate is included in "all phosphates" so it is insoluble and can't become an aqueous solution.
Magnesium Phosphate (Mg₃(PO₄)₂) would not make an aqueous solution because it is insoluble in water.
A solution is a homogeneous mixture of one or more solutes dissolved in a solvent.
solvent: the substance in which a solute dissolves to produce a homogeneous mixture.solute: the substance that dissolves in a solvent to produce a homogeneous mixture.According to the solubility rule, all phosphates are insoluble in water except sodium and potassium phosphates and thus magnesium phosphate does not form an aqueous.
