D. March because it is just below the 1 million marker on the graph and it is the only one that low.
Water<span> can </span>dissolve salt<span> because the positive part of </span>water<span> molecules attracts the negative chloride ions and the negative part of </span>water<span> molecules attracts the positive sodium ions. The amount of a substance that can </span>dissolve<span> in a liquid (at a particular temperature) is called the solubility of the substance. So the solute is the salt and the solvent is the water. I believe that is correct.</span>
Sry,I only know the answer of q2
Chlorine is a non metal because it is bad conductor of heat and sodium is a metal because it is good conductor of heat.
The 3 ways in which metal is different from non metal are given below:
1)metal are good conductor of heat but nonmetal are bad conductor of heat.
2)metals are malleable but non metal aren't malleable.
3)metals are generally ductile but non metal aren't ductile.
Hope it will helpyou!
P= mv
where p is momentum
m is mass
v is velocity
so it's given p= 100kgm/sec
v= 4m/s
so putting in the formula
100= m × 4
m = 25kg
