How does weathering change rock and minerals
Phantasy [73]

Weathering is the process of breaking large rocks and boulders into much smaller ones. Weathering can be brought about by wind and water mostly. Sometimes even biological forces account for some types of weathering.

If an individual proton has mass 1.007825 amu, and an individual neutron has mass 1.008665 amu, what's the calculated mass of a
german

Answer:

C) 237.96682 amu

Explanation:

The symbol for neptunium-236 is given as;

²³⁶₉₃Np

This element has 93 protons and (236 - 93 = 143) neutrons.

Mass Number =Total mass of Protons + Total mass of neutrons

Total Mass pf protons = 93 * 1.007825 amu, = 93.727725 amu

Total mass of Neutrons = 143 * 1.008665 amu = 144.239095 amu

Mass = 144.239095 + 93.727725  = 237.96682 amu

Correct option is option C.

A sample of Ammonia gas at 650mmHg and 15 degree has a mass of 56.8g.calculate the volume occupied by the gas. Take N=14, H=1,R=
avanturin [10]

Answer:

The first thing we have to do is change and state all the units so that we can use our ideal gas law equation (PV = nRT).

650 mmHg is a pressure unit, we have to convert this to kiloPascals. We know that 760 mmHg gives us 101 kPa.

650 \ mmHg \ * \ \frac{101kPa}{760 mmHg} = 86 \ kPa

P = 86kPa

T = 15°C + 273K = 288K

R (Gas constant) = 8.31 kj/mol  

Molar mass of Ammonia (NH_{3}) = (1 x 3) + (14) = 17g/mol

n (moles) = \frac{mass}{molar \ mass} = \frac{56.8}{17} = 3.34 mol

V = ?

Rearrange the equation to solve for Volume:

V = \frac{nRT}{P}

Substitute the values inside:

V = \frac{(3.34)(8.31)(288)}{(86)} = 93 L (rounded)

<u>Therefore 93 L of volume is occupied by the ammonia gas.</u>

<u></u>
