How much mass defect is required to release 5.5 x 1020 J of energy?
Montano1993 [528]

Answer : The mass defect required to release energy is 6111.111 kg

Explanation :

To calculate the mass defect for given energy released, we use Einstein's equation:

E=\Delta mc^2

E = Energy released = 5.5\times 10^{20}J

\Delta m = mass change = ?

c = speed of light = 3\times 10^8m/s

Now put all the given values in above equation, we get:

5.5\times 10^{20}Kgm^2/s^2=\Delta m\times (3\times 10^8m/s)^2

\Delta m=6111.111kg

Therefore, the mass defect required to release energy is 6111.111 kg

Which statement correctly describes an atom of the element helium? (9)
Luden [163]

C. An atom of helium has its valence electrons in its first energy level, it wouldn't and can't satisfy the Octet rule as it only has 2 electrons, but with 2, it has a full shell, as the first energy level can hold only 2 electrons.

the temperature is increased, the position of equilibrium moves to the left, and the yield of ammonia decreases.
igomit [66]

Answer:i don't rlly get the question but this is what i found on the internet :/

Explanation:

When the temperature is increased, the position of equilibrium moves in the endothermic direction to reduce the temperature. ... This means that as the temperature is increased, the position of equilibrium moves to the left, and the yield of ammonia decreases.

You try to measure out exactly 5.0 milliliters of water by eye into each of five test tubes. When you go back to check the volum
jeka94

Answer:

The volumes are both, accurate and precise.

Explanation:

In the measurement of a set, precision refers to how much coincidence exists in the measurements of an specific value, as the measurements are close, we can say the volumes are precise.

Accuracy means the agreement that exists between the average of one

large series of measurements and the value of  measurement

Media is 4,96 ml and I wanted to measure 5 ml. It is also close.

What elements would likely form an ionic bond?
Nutka1998 [239]

Answer:

b. Mg & Cl

a. transferred

46

Explanation:

Ionic bonds form between metals and non-metals when electrons are transferred from one specie to another.

  • The electrostatic attraction from the resulting ions forms the ionic bonds.
  • A metal is electropositive and will readily donate electrons
  • A non-metal is electronegative and will accept electrons.
  • This creates two oppositely charge ions that attracts by means of ionic bonding.

Since Mg and Cl are the only metal - non-metal pair, and ionic bond will form between them.

2.

  In the specie;

          ₄₇Ag¹⁺

47 is the atomic number of the element Ag.

The atomic number is the number of protons in an atom. For a specie in neutral state, the number of protons and electrons are the same.

  • When an atom loses electron, it becomes positively charged.
  • Here Ag has lost one electron and then, the number of electrons becomes 46.
  • The number of protons is still 47
