What statement is true about isotopes?

Chemistry
1 answer:
ipn [44]3 years ago
4 0

Answer:

D. THEY HAVE THE SAME NUMBER OF PROTONS AND ELECTRONS BUT DIFFERENT NUMBERS OF NEUTRONS.

Explanation:

Isotopy is the phenomenon that explains the various variants of an element having different number of neutrons but the same number of protons and electrons.

Isotopes are variants of a particular chemical element that possesses the same number of proton or atomic number but different mass number. The atomic number of an element is the number of protons and electrons contained by the element while the mass number is the sum total of the number of protons and neutrons in the nucleus of the elements.

Examples of isotopes are the hydrogen atom, chlorine element and so on.

Hydrogen has three isotopes which are hydrogen H, Deuterium and Tritium. Chlorine has two isotopes which are chlorine 35 and chlorine 37.

So the true options about isotopes is that they possess the same number of protons and electrons but different numbers of neutrins.

algol13

Answer:

P_2=135.73psi

Explanation:

Hello,

In this case we use the Boyle's law which allows us to understand the volume-pressure behavior as an inversely proportional relationship:

V_1P_1=V_2P_2

Whereas we solve for P_2 as the required final pressure:

P_2=\frac{V_1P_1}{V_2} =\frac{27.0L*14.7psi}{3.00L}\\ \\P_2=135.73psi

Best regards.

How many miles of NaOH will completely react with 10.0 mL of 1.0 M HCl?
Naddik [55]
The reaction between 1 mole of NaOH and 1 mole of HCl creates 1 mole of NaCl and 1 mole of water. Meaning that the moles of HCl needs to equal that of NaOH for the solution to be considered equalized. That being said, you first need to find the numbers miles of HCl by multiplying the volume by the molarity to get 0.01 moles HCl. (1Mx0.01L=0.01). That means that you need 0.01 moles of NaOH. I hope that helps. Let me know if anything is unclear.

In water, hydrogen bonds are best described as _____.
Elina [12.6K]

Answer: Option D) covalent bonds between water molecules

In water, hydrogen bonds are best described as covalent bonds between water molecules

Explanation:

The hydrogen bonds between water molecules are covalent bonds because they are formed when oxygen attract the lone electron in hydrogen, thus resulting in the formation of a partially negative charge on the oxygen atom and a partially positive charge on two hydrogen atoms

Thus, the sharing of electrons between oxygen and hydrogen atoms is responsible for the covalent bonds between water molecules
