when glaciers (slowly) glide down a mountain they carry down earth and rock and brings it down. After the glacier has completely melted the earth from the mountain id deposited to the lower ground.

Like flowing water, flowing ice erodes the land and deposits the material elsewhere. Glaciers cause erosion in two main ways: plucking and abrasion.
Plucking is the process by which rocks and other sediments are picked up by a glacier. They freeze to the bottom of the glacier and are carried away by the flowing ice.
The other way you'll need more informations because my Knowledges are limited by here.

Answer:

14.2L at STP

Explanation:

Based on the problem, 2 moles of NH3 produce 6 moles of HF. To solve this question we have to convert the mass of NH3 to moles. With the chemical equation find the moles of HF and using PV = nRT find the liters of HF:

Moles NH3 -Molar mass: 17.031g/mol-

3.6g NH3 * (1mol / 17.031g) = 0.211 moles NH3

Moles HF:

0.211 moles NH3 * (6mol HF / 2mol NH3) = 0.634 moles HF

Volume HF

PV = nRT; V = nRT/P

Where V is volume in liters, n are moles of the gas = 0.634 moles, R is gas constant = 0.082atmL/molK, T is absolute temperature = 273.15K at STP and P is pressure = 1atm at STP.

Replacing:

V = 0.634moles*0.082atmL/molK*273.15K / 1atm

V = 14.2L at STP

when chemical x is added to a certain liquid, it breaks down into chemicals y and z. it is not possible to simplify chemicals y

Hatshy [7]

Elements are the same type of atoms, so there is nothing else to separate. Hydrogen has hydrogen atoms, and no other kind. Therefore nothing can be taken out of it anymore. Chemical x is a mixture, made by y and z. Nothing can make up y and z but themselves.

The total volume in milliliters of a glucose-water solution is given by the equation below: V = 1001.93 + 111.5282m + 0.64698m^2

vagabundo [1.1K]

Answer:

a. Vₐ = 111.5282 + 1.29396m

b. For m = 0.100m; Vₐ = 111.6576

Explanation:

The partial molar volume of compound A in a mixture of A and B is defined as :

$V_a = \frac{dV}{dn_a}$
