Answer:
The differemt isotopes that differ in atomic mass
Explanation:
Answer:
The answer is
<h2>0.075 kg</h2>
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
<h3>mass = Density × volume</h3>
From the question
density = 762 kg/m³
We must first convert the volume from cm³ to m³
So 99 cm³ will be
So the mass of the material is
We have the final answer as
<h3>0.075 kg</h3>
Hope this helps you
Answer:
Mass= 2.77g
Explanation:
Applying
P=2.09atm, V= 1.13L, R= 0.082, T= 291K, Mm of N2= 28
PV=nRT
NB
Moles(n) = m/M
PV=m/M×RT
m= PVM/RT
Substitute and Simplify
m= (2.09×1.13×28)/(0.082×291)
m= 2.77g
Answer:

Explanation:
The best answer is A.
The alimentary canal also called the digestive tract is the pathway by which food enters the body and solid wastes are expelled. The alimentary canal includes the mouth, pharynx esophagus, stomach, small intestine, large intestine and anus.
Food is converted into essential nutrients that are absorbed into the body and eliminates unused waste material. It is essential to good health because if the digestive system shuts down, the body cannot be nourished or rid itself of waste.
