Answer:
I think probably diet because the type of food you put in your body (if it has high calorie or sodium) can severley affect your overall health and therefore affect your bpm(beats per minute)
Explanation:
Answer:
the ionic radius of the anion 
Explanation:
From the diagram shown below :
The anion 
is located at the corners
The cation 
is located at the body center
The Body diagonal length = 
∴ 
Given that :
(i.e the ratio of the ionic radius of the cation to the ionic radius of
the anion )
Also ; a = 664 pm
Then :
Therefore, the ionic radius of the anion
Answer:
Option D - 10,000 years ago in the Middle East
Answer:
The lowest whole number mass ratio of nitrogen that combines with a given mass of oxygen is 1:1
Explanation:
In compound A, we have 14 g of nitrogen combine with 16 g of oxygen
In compound B, we have 14 g of nitrogen combine with 32 g of oxygen
Therefore, we have
A B
Ratio of molar masses 14:16 14:32
Mass of O that combine with 1 g of N 1.14 2.29
Dividing by the smallest mass ratio 1 2
Therefore the lowest whole number mass ratio at which oxygen and nitrogen can combine = 1:1.
Answer:
The image is not accurate because
the heavier atoms are moving faster than the lighter ones
but the lighter ones must move faster than the heavier ones.
Explanation:
The image depicts the atoms of two different elements; atoms of lighter and heavier elements.
And the rate of diffusion (movement of atoms) of an element is inversely proportional to the square root of its molecular.
⇒ As the weight increases, the rate of diffusion (movement of atoms) decreases.
And as the weight decreases, the rate of diffusion (movement of atoms) increases.
so, heavier atoms move slowly compared to lighter atoms.
The image is not accurate because
the heavier atoms are moving faster than the lighter ones
but the lighter ones must move faster than the heavier ones.
