Metals generally form cations, meaning they become positively charge - this positive charge is due to the loss of electrons.

Answer: -

Cation

Explanation: -

Metals have low ionization enthalpy. So they tend to lose it's electrons to fulfill octet.

Upon losing electrons, a metal atom has more protons than neutrons.

The electrical neutrality of the atom is no longer there.

The metal atom after losing electron has a positive charge.

They are referred to as cations.

Lower the group of periodic table an element is found, more is it's tendency to form cations.

2.00 L of 0.800 M NaNO3 must be prepared from a solution known to be 2.50 M in concentration.How many mL are required? Plus don'

Morgarella [4.7K]

Answer:

1.36 × 10³ mL of water.

Explanation:

We can utilize the dilution equation. Recall that:

$\displaystyle M_1V_1= M_2V_2$

Where M represents molarity and V represents volume.

Let the initial concentration and unknown volume be M₁ and V₁, respectively. Let the final concentration and required volume be M₂ and V₂, respectively. Solve for V₁:

$\displaystyle \begin{aligned} (2.50\text{ M})V_1 &= (0.800\text{ M})(2.00\text{ L}) \\ \\ V_1 & = 0.640\text{ L} \end{aligned}$

Therefore, we can begin with 0.640 L of the 2.50 M solution and add enough distilled water to dilute the solution to 2.00 L. The required amount of water is thus:
$\displaystyle 2.00\text{ L} - 0.640\text{ L} = 1.36\text{ L}$

Convert this value to mL:
$\displaystyle 1.36\text{ L} \cdot \frac{1000\text{ mL}}{1\text{ L}} = 1.36\times 10^3\text{ mL}$

Therefore, about 1.36 × 10³ mL of water need to be added to the 2.50 M solution.

Answer:

The first theory states that the rings formed at the same time as the planet. Some particles of gas and dust that the planets are made of were too far away from the core of the planet and could not be squashed together by gravity. They remained behind to form the ring system.

basically all of the molecules in the can of soda started to stop moving due to the compression and change of temperature. the ice had frozen the molecules and which then made the can of soda nice and cold lol
