Which substance will form a solution when mixed with solid sodium chloride?
OA. NaO₂ (s)
O B. Cl₂(g)
O C. CCl4(0)
OD. CH₂OH()

Answer:

Here's your answer.

M(C3H8) = 44 g/mol

n(C3H8) = 5000 (g)/44 (g/mol) = 113,6 mol

[tex] N = n \times N_{a} = 113,6 \times 6,02 \times {10}^{23} \\ \\ = 684,1 \times 10 ^{23} \sf{molecules} [/tex]

The amount of time of contact, the area of contact, and the specific heats of the substances. Hence, option A is correct.

The heat in calories is required to raise the temperature of one gram of a substance one degree Celsius.

Factors that affect the rate of heat flow include the conductivity of the material, the temperature difference across the material, the thickness of the material, and the area of the material.

Different materials have greater or lesser resistance to heat transfer, making them better insulators or better conductors.

The amount of time of contact, the area of contact, and the specific heats of the substances.

Hence, option A is correct.

Answer: The answer is C and D

B: If a substance undergoes a physical change, then it will retain most of its original properties because no new substance is formed.

C: If a substance undergoes a chemical change, then it will not retain its original properties because a new substance is formed.

Explanation: I took the test on edg

The given equilibrium reaction indicates the reaction between carbon monoxide and the oxygen and forms carbon dioxide. In this reaction, by increasing the concentration of the carbon monoxide, the equilibrium shifts towards the right. Since, the reactant concentration increases, the equilibrium stress decreases the concentration of the reactants and therefore, the equilibrium shift towards the right side of the equation.

reaction indicates that carbon monoxide reacts with oxygen and forms carbon dioxide gas.

By increasing the concentration of carbon monoxide image, the equilibrium in the reaction shifts towards the right.

The effect of change of pressure, concentration and temperature on the state of equilibrium can be predicted with the help of a principle known as Le Chatelier's principle. Here by increasing the concentration of CO₂, the amount of CO formation can increase.

If a system in equilibrium is subjected to a change in concentration, pressure or temperature, the equilibrium shifts in the direction that tends to reduce or to counteract the effect of change. When the concentration of any substance in equilibrium is increased, the equilibrium shifts in the direction which decreases the concentration of that substance.

On other hand, increasing the concentration of any of the products results in shifting the equilibrium in the backward reaction forming more products. So here increasing the amount of CO₂, shifts equilibrium in the backward direction and forms more amount of CO.

Answer:

I believe it is useful as it shows how electrons are distributed in the shells (energy levels) of an iron atom. An atom is the smallest particle of an element that can take part in a chemical reaction. It contains the nucleus and the shells (energy levels). the nucleus contains protons and neutrons while the shells contain electrons.
