<u>Answer:</u> The correct answer is Option B.

<u>Explanation:</u>

Beryllium is the 4th element of the periodic table having electronic configuration 1s^22s^2. This element belongs to Group 2 of the periodic table.

Elements that belong to same group show similar chemical properties because they have same number of valence electrons.

For the given options:

<u>Option A:</u> Hydrogen

This element belong to group 1 of the periodic table.

<u>Option B:</u> Calcium

This element belong to group 2 of the periodic table. Thus, this will show similar chemical properties to beryllium.

<u>Option C:</u> Lithium

This element belong to group 1 of the periodic table.

<u>Option D:</u> Boron

This element belong to group 13 of the periodic table.

Hence, the correct answer is Option B.

Which of the following is true for balancing equations?
nataly862011 [7]

Answer:

D) There must be equal number of atoms of each elements on both sides of equation.

Explanation:

The balancing equation must have equal number of atoms of each elements on both sides of equation.

The balance equation shoes mass is conserved thus followed the law of conservation of mas.

Law of conservation of mass:

According to the law of conservation mass, mass can neither be created nor destroyed in a chemical equation.

Explanation:

This law was given by french chemist  Antoine Lavoisier in 1789. According to this law mass of reactant and mass of product must be equal, because masses are not created or destroyed in a chemical reaction.

For example:

In given photosynthesis reaction:

6CO₂ + 6H₂O + energy → C₆H₁₂O₆ + 6O₂

there are six carbon atoms, eighteen oxygen atoms and twelve hydrogen atoms on the both side of equation so this reaction followed the law of conservation of mass.

Question 1
Salsk061 [2.6K]

Answer:

Part A:

"360 grams of NaCl can be dissolved in 1 L water. So, 2000 grams sugar can be dissolved in 1 L water then we can say that the solubility of salt is lesser in water as to sugar and both heightened by increasing the temperature. If we make a batch of 800 L we can add sugar, 1600 kg at 25 0c. We can add salt is 288 kg at 25 0c and the ingredient tomato is having low solubility."

The compound 1-iodododecane is a nonvolatile liquid with a density of 1.20g/ml. the density of mercury is 13.6g/ml. part a what
valina [46]

As the atmospheric pressure is, P = dgh

Here d is the density of the mercury,

g is gravitation = 9.8 m/s²

h is height of the column, P = 751 torr = (751 torr × 1 atm / 760 torr) (101325 Pa) (1 N/m² / 1 Pa) = 100125 N/m²

Where, 1 N = 1 Kg / ms²

Thus, P = 100125 Kg / m³. s²

Therefore, height of the mercury column, when the atmospheric pressure is 751 torr,

h = P / gd

= (100125 kg / m³. s²) / (9.8 m/s²) (13.6 × 10³ kg / m³) = 0.751 m

As, d₁h₁ = d₂h₂

Here, d₁ is the density of the non-volatile liquid = 1.20 g/ml

d₂ is the density of the mercury = 13.6 g/ml

h₂ = 0.751 m

Thus, putting the values we get,

h₁ = d₂h₂ /d₁ = 13.6 g/ml × 0.751 m / 1.20 g/ml

= 8.5 m

Why do we not know yet if we live in multiverse
kherson [118]

The people of he world believe and they don't believe.

I,myself, think we do land don't live in multiverse.

Why: Because in science I hear that there are many universes out there that need to b explored.

Not: Because if we did, don't you think that Astronauts and the U.S. would try and find different universes.

I hope I helped you!:)
