Sr is the atom that has the lower ionization energy.

Ionization is the procedure by using which ions are shaped by the gain or loss of an electron from an atom or molecule. If an atom or molecule gains an electron, it becomes negatively charged (an anion), and if it loses an electron, it will become definitely charged (a cation). energy may be misplaced or received within the formation of an ion.

Ionization or Ionisation is the manner by means in which an atom or a molecule acquires a negative or superb price through gaining or dropping electrons, regularly along with other chemical modifications. The resulting electrically charged atom or molecule is referred to as an ion.

while sodium and chlorine integrate to make salt, the sodium atom offers up an electron resulting in a wonderful charge, while chlorine receives the electron and will become negatively charged as an end result.

If an object has two forces acting on it how can the next force equal 0

Flura [38]

If the forces are equal and in opposite directions, the net force will equal zero.

Consider a tug-of-war team. If they are pulling with equal forces against each other, the red cloth on the rope will not move.

F = ma

The cloth is not moving, so a = 0 and the net force F = 0.

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.

What happens when a substance undergoes a physical change? Some physical properties change, but the substance keeps its identity

elena55 [62]

Some physical properties change, but the substance keeps its identity.

When dealing with these kind of questions, understand that the keyword here is physical change. Thus, all options that says no physical properties change are WRONG. So this leaves us with only 2 answers left. However, this is a physical change, no chemical change. Thus, the substance will keep its identity and not change.

A sound waves frequency is 4hz and it’s wavelength is 8 meters. What is the waves speed

AlladinOne [14]

Answer:

Speed of wave = 32 ms⁻¹

Explanation:

Given data:

Frequency of wave = 4 Hz

Wavelength of wave = 8 m

Speed of wave = ?

Solution:

Formula:

Speed of wave = wavelength × frequency

Now we will put the values.

Speed of wave = 8 m × 4 Hz

Hz = s⁻¹

Speed of wave = 32 ms⁻¹
