The final temperature of the cup may be less than accurate thereby affecting the entire results of the experiment carried out using the cup.

A styrofoam cup is an insulated material. A styrofoam cup prevents heat gain or looses from the cup. Heat is gained by the water inside the styrofoam cup. The cup prevents exchange of energy with the environment.

When water is lost from the styrofoam cup, the final temperature of the cup may be less than accurate thereby affecting the entire results of the experiment carried out using the cup.

Answer:The number of BH+ Molecules will increase , and the number of water molecules will decrease

Explanation:

The number of OH- ions will increase, and the number of BH molecules will decrease.

Option (3) is correct.

In the given base solution equation, B + H₂O = BH⁺ + OH⁻, when the strength of the base is increased, more B molecules will react with water to form BH⁺ and OH⁻ ions. This happens because a stronger base donates more OH⁻ ions into the solution, increasing its concentration.

As the base becomes stronger, more B molecules will participate in the reaction, forming fewer BH⁺ molecules since they are being converted to BH⁺ ions. Simultaneously, the increased concentration of OH⁻ ions means that the number of OH⁻ ions in the solution will increase.

Overall, the change in the number of particles can be summarized as follows:

The number of BH molecules will decrease.

The number of OH⁻ ions will increase.

This change reflects the increase in the concentration of OH⁻ ions, which is a characteristic of a stronger base solution.

The mass of water that can be boiled by 1 g of gasoline by raising its temperature from 20 °c to 100 °c is  17.6 g.

Now, we know that energy can not be created nor destroyed but it can be converted from one form to another.

The heat produced by the gasoline is equal to the heat gained by water. Mathematically;

1g ×  45 × 10^3 = [1 g × 4.18  × (100 - 20) + 2540m]

45 × 10^3 = 334.4 + 2540m

45 × 10^3 - 334.4 =  2540m

m =  45 × 10^3 - 334.4 /2540

m = 17.6 g

The mass of water that can be boiled by 1 g of gasoline by raising its temperature from 20 °c to 100 °c is 17.6 g.

Answer:

KBr final solution:

V = 250mL --> 0.25L

Concentration/Molarity = 1.5 mol/L

To find the amount of moles of KBr here, just multiply the volume by the concentration (0.25 x 1.5 = 0.375 mol)

So the amount of moles for KBr is 0.375 mol. Now we know that the mass divided by the molar mass (the atomic mass values of K and Br in the periodic table added together) would give us the amount of moles aswell.

n = moles

m = mass

M = molar mass

n = m/M

so if we rearrange this equation to find mass, we would get:

m = n x M

Molar mass for KBr: (39.09) of K + (79.90) of Br = 118.99

m = 0.375 mol    x    118.99

m = 44.62g

Therefore 44.62g of KBr is needed to make 250mL of a 1.5 M KBr solution.

Two balloons hold two different gases. The gases are held at the same pressure, volume, and temperature. Which quantity can differ between the two gases?(1 point) the gas constant of each gas the gas constant of each gas the molar volume of each gas the molar volume of each gas the mass of each gas the mass of each gas the number of moles of each gas

the number of moles of each gas

PV = nRT

The gases have the same P.V, T and n

R is constant AND SO constant for both

the only difference is the molar mass of the gas

for the same number of moles, the  balloons will have different weights depending on the gas  

so the answer is

the mass of each gas

Explanation:

First organisms to convert solar energy to chemical energy were the organisms which are called as cyanobacteria.

Energy which is stored in the chemical bonds of chemical compounds is called chemical energy.Chemical energy is released during the occurrence of chemical reaction.Reactions wherein energy is given out in the form of heat is called exothermic reactions.

Chemical energy can be converted to other forms of energy like electrical energy during the process of electrolysis and to thermal energy as in the case of thermal engines.

It can also be converted to kinetic energy during explosions . It is stored in batteries, coal, biomass, food, vehicle air bags,etc.During digestion chemical energy is converted to mechanical and thermal energy.
