Consider the atom with the chemical symbol Ru.

Chemistry
1 answer:
Vinil7 [7]1 year ago
4 0

Answer: 97

Explanation:

The element Ru is <u>Ruthenium</u> which has <u>44 protons</u>.

In this case, our atom is an isotope with <u>53 neutrons</u>.

With this information, we can use the mass number formula to find this atom's mass number.

mass number = protons + neutrons

mass number = <u>44 protons</u> + <u>53 neutrons</u>

mass number = <u>97</u>

Solnce55 [7]

Answer:

false

Explanation:

As we know that in sodium-potassium pump .          

sodium potassium move 3Na+ outside the cells          

and  moving 2k+ inside the cells                        

so that we can say that given statement is false    

Answer FALSE

A 36.4-l volume of methane gas is heated from 25°c to 88°c at constant pressure. what is the final volume of the gas?
nignag [31]
<span>using the law pv=nrT and equating these you get the equation v1/t1 = v2/t2 since pressure is constant it also cancels with n and r. show that v1=36.4, t1 = 25 + 273.15 and t2 = 88 +273.15. 273.15 is the Kelvin conversion. then solve for v2. This is 44.1 L.</span>

Airida [17]

Answer:

d. each of the above (A, B, and C) occurs.

Explanation:

When an ionic species dissolves in water , the ionic compound dissociates into cation and anion , and the cation interacts with the negative end of the water molecules , and the anion interacts with the positive end of the water molecule .

During the process of dissolution , the interaction between , solvent - solute overcome the interaction between solute - solute molecules .

Hence , From the question , all the statement given are correct .
