Answer:

146.885 kPa

Explanation:

1 atm= 101.3 kPa =1.013 barr= 760 torr = 760 mmHg= 14.7 psi

So to convert atm to kpa we would multiply 1.45 by 101.3 which gives us 146.885.

1.45atm× $\frac{101.3 kPa}{1 atm}$ =146.885 kPa

A meteor falls toward Earth's surface. Given that the acceleration due to

ICE Princess25 [194]

Answer:

E = 147000 J

Explanation:

Given that,

The mass of meteor, m = 50 kg

The altitude of the meteor, h = 300 m

We need to find the potential energy of the meteor. The formula for the potential energy is given by :

$E=mgh$

Put all the values,

$E=50\times 9.8\times 300\\\\E=147000\ J$

So, the required potential energy is equal to 147000 J.

How many grams of aluminum is produced when 82.4 grams of aluminum chloride

yKpoI14uk [10]

Answer:

16.6 g of Al are produced in the reaction of 82.4 g of AlCl₃

Explanation:

Let's see the decomposition reaction:

2AlCl₃ → 2Al + 3Cl₂

2 moles of aluminum chloride decompose to 2 moles of solid Al and 3 moles of chlorine gas.

We determine the moles of salt:

82.4 g . 1mol/ 133.34g = 0.618 moles

Ratio is 2:2. 2 moles of salt, can produce 2 moles of Al

Then, 0.618 moles of salt must produce 0.618 moles of Al.

Let's convert the moles to mass → 0.618 mol . 26.98g /mol = 16.6 g

If 4.12 l of a 0.850 m-h3po4 solution is be diluted to a volume of 10.00 l, what is the concentration of the resulting solution?

statuscvo [17]

The process in which the concentration of the solution is lessened by the addition of water is said to be dilution and equation of dilution relates the initial concentration and volume of stock solution with the final concentration and volume of the solution.

Formula is given by:

$C_{1}V_{1}=C_{2}V_{2}$ (1)
