Answer: Oxidation state of Arsenic in the given compound is +3 and that of oxygen is -2.

Explanation:

We are given a compound having formula $As_2O_3$ and we need to find the oxidation state of all the atoms in this compound. There are 2 different atoms present in this : Arsenic and Oxygen

Oxidation state is the number which is assigned to an element in a compound which represents the number of electrons lost or gained by an atom in a compound.

Oxidation state of oxygen as -2 which is same always. Now, to calculate the oxidation state of Arsenic, we take the oxidation state of it be 'x'

As, there are two arsenic atoms and three oxygen atoms, then:

$\Rightarrow 2(x)+3(-2)=0\\\Rightarrow 2x-6=0\\\Rightarrow x=+3$

Hence, oxidation state of Arsenic in the given compound is +3 and that of oxygen is -2.

What is the correct scientific notation for 640,000,000? Question 5 options: 6.4X10^8 6.4X10^10 64X10^10 640X10^8

N76 [4]

For very large numbers, it is much more convenient to use scientific notation. To do this, detect first the position of the decimal point. For whole numbers, the decimal point is place implicitly after the very last digit. Then, move this decimal point to the left until you reach to the last digit. In this case, you moved 8 places until you reach 6.4. Because the number is more than 1, the exponent would have a positive sign. Hence, the scientific notation would be 6.4×10⁸.

If two separate containers A and B have the same volume and temperature, but container A has more gaseous molecules than B, then

topjm [15]

Answer:

Higher pressure, is the right answer.

Explanation:

The A will have a higher pressure. Since we have given the volume and temperature is same in both containers A and B. Below is the calculation for proof that shows which container has the higher pressure while keeping the volume and temperature the same.

$So, \ V_A = V_B \\\frac{n_A T_A}{P_A} = \frac{n_B T_B}{P_B} \\Here, \ T_A = T_B \\P_A = \frac{n_A}{n_B} \times P_B \\\frac{n_A}{n_B} > 1 \\\frac{P_A}{P_B} > 1 \\P_A > P_B \\$

Therefore, the container “A” will have higher pressure.

Evaluate the exponential expression (−2)6.

Olegator [25]

A general exponential expression is something like:

A^n

This means that we need to multiply the number A by itself n times.

Using that we will get (-2)^6 = 64

With that definition, we can rewrite:

(-2)^6 = (-2)*(-2)*(-2)*(-2)*(-2)*(-2)

So we just need to solve the above expression.

Also, remember the rule of signs:

(-)*(-) = (+)

We will get:

(-2)*(-2)*(-2)*(-2)*(-2)*(-2) = [(-2)*(-2)]*[(-2)*(-2)]*[(-2)*(-2)]

= 4*4*4 = 16*4 = 64

Then we got:

(-2)^6 = 64

What do animals use to clone from a cell in one parent

user100 [1]

Cloning occurs when identical twins, triplets, and so on are born or when a cutting from a plant is used to generate another plant. It also occurs in organisms that reproduce by asexual reproduction, such as bacteria and yeast.
