The new pressure when the aerosol can is heated to 450°C is 3.64atm.

HOW TO CALCULATE NEW PRESSURE:

The new pressure can be calculated by using the formula below:

P1/T1 = P2/T2

Where;

P1 = initial pressure (atm)T1 = initial temperature (K)P2 = final pressure (atm)T2 = final temperature (K)According to this question, P1 = 1.5atm, T1 = 25°C + 273 = 298K, P2 = ?, T2 = 450°C + 273 = 723K1.5/298 = P2/723723 × 1.5 = 298 × P21084.5 = 298P2P2 = 1084.5 ÷ 298P2 = 3.64atmTherefore, the new pressure when the aerosol can is heated to 450°C is 3.64atm.

Answer from: brookekolmetz

3.6atm

Explanation:

Given parameters:

Initial pressure = 1.5atm

Initial temperature = 25°C = 25 + 273 = 298K

Final temperature = 450°C = 450 + 273 = 723K

Unknown:

Final pressure = ?

Solution:

To solve this problem, we use the combined gas law and we assume a constant volume. The expression to solve this is given below;

$\frac{P_{1} }{T_{1} }$ = $\frac{P_{2} }{T_{2} }$

P and T are temperature values

1 and 2 are initial and final states

Insert the parameters and solve;

$\frac{1.5}{298}$ = $\frac{P_{2} }{723}$

P₂ = 3.6atm

Answer from: Quest

- calcium has greater affinity to bond with electron receptors than hydrogen does and hence, it has the ability to replace hydrogen in most of its compounds.

- lithium has 2 valence electrons in the product because it can make only 1 bond with hydrogen. beryllium has 4 valence electrons in the product because it can only make 2 bonds. it has fewer electrons than neon and can react with electron donors. each hydrogen has 2 valence electrons, the same as helium.

- the covalent bond formed between carbon and hydrogen is polar because carbon is more electronegative than hydrogen and it attracts the bonded electron pair closer to itself, thus giving hydrogen a partial positive charge.

- a hydrogen bond is a relatively weak bond that hydrogen atoms make with the electronegative atoms nitrogen, oxygen or fluorine.

so the best choice is a.) 2 calcium (ca) atoms

Answer from: Quest

when the volume of gas is changed from 717.73 ml to 852 ml the temperature will change from 315 c to 452 c

calculation

this is calculated using the charles law formula

that is, v1/t1 = v2/t2

v1=?

t1 = 315 c into kelvin = 315 +273 = 588 k

v2 = 852 ml

t2 = 425c + 273 =698 k

make v1 the subject of the formula ( by multiplying both side by t1)

v1=( v2 xt1) / t2

v1= (852 ml x 588 k)/ 698 k= 717.73 ml
