Ok then! So mitosis is when a cell splits and doesn't lose/gain any chromosomes. In meiosis the chromosomes join and split evenly at the cell's "poles". Chromosomes will be lost evenly through this process.

12.Calculate the wavelength of an object moving with a velocity of 5 x105 m s-1

uranmaximum [27]

Answer:

Wavelength, $\lambda=3.3\times 10^{-18}\ m$

Explanation:

We have,

Velocity of the object, $v=5\times 10^5\ m/s$

Mass of the object, $m=4\times 10^{-22}\ kg$

It is required to find the wavelength of the object. The relation between wavelength and velocity of the object is given by :

$\lambda=\dfrac{h}{mv}$

h is Planck's constant

$\lambda=\dfrac{6.6\times 10^{-34}}{4\times 10^{-22}\times 5\times 10^5}\\\\\lambda=3.3\times 10^{-18}\ m$

So, the wavelength of the object is $3.3\times 10^{-18}\ m$ .

How many moles of NaCl are created as a result of decomposing 12 grams of NaClO3? (molar mass of Na=23, Cl=35, O=16)

Harman [31]

Answer: 0.113 moles of NaCl are created as a result of decomposing 12 grams of $NaClO_3$ .

Explanation:

To calculate the moles :

$\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}$

$\text{Moles of} NaClO_3=\frac{12g}{106.5g/mol}=0.113moles$

The balanced chemical equation for decomposition of $NaClO_3$ is:

$2NaClO_3\rightarrow 2NaCl+3O_2$

According to stoichiometry :

2 moles of $NaClO_3$ give = 2 moles of $NaCl$

Thus 0.113 moles of $NaClO_3$ give = $\frac{2}{2}\times 0.113=0.113moles$ of $NaCl$

Thus 0.113 moles of NaCl are created as a result of decomposing 12 grams of $NaClO_3$ .

What term is used when heat is transferred from one piece of matter to another until they are of equal temperature?

IgorC [24]

thermal contact

When heat flows from one object or substance to another it is in contact with, the objects or substances are said to be in thermal contact. The state where objects in thermal contact with each other reach the same temperature, no heat flows between them.
