Answer:
from,
moles,n = <u>number</u><u> </u><u>of</u><u> </u><u>particles</u><u>,</u><u> </u><u>N</u>
Avogadro constant
N = 8.27 * 6.022×10^23
N = 4.98 × 10^ 24particles.
In 8.27 moles of SiH, there are
4.98 × 10^24particles.
Answer:
See below
Explanation:
Q = m c T c = specific heat T = temp change Q = heat joules
32 = 4 c 40 <u> c = .2 J/g-C</u>
314 to 344 k is a change of 30 K
Q = m c T
= 4 * .2 * 30 = <u>24 Joules </u>
Answer:
8g/mL
Explanation:
Density = Mass/Volume
There is 5.6g of Iron added to the water of 23.60mL and it rose by 0.7mL.
Density = 5.6g/0.7mL of Iron.
Answer:
B. Reese's yard
Explanation:
Because Reese's yard is full of rocks, rock's don't absorb water, while Chris' yard is only soil, which will make his yard absorb water quicker.
On oxidation of aldehydes produces carboxylic acid functional group.
The product of oxidation of aldehydes depends upon whether the reaction occur in acidic medium or alkaline condition.
If oxidation of aldehydes occurs under acidic condition the product is carboxylic acid but if oxidation of aldehydes occurs under alkaline condition then reduce as well as oxidized product obtained which is known as disproportional product.
The oxidation of aldehydes occur through potassium dichromate, potassium permanganate or many more. The oxidation of aldehydes in the presence of base is known as cannizzaro's reaction.
