Answer:

VELOCITY

Explanation:

VELOCITY IS THE SPEED AND DIRECTION OF MOVEMENT

Explanation:

velocity

reason: The velocity of an object is the rate of change of its position with respect to a frame of reference, and is a function of time. Velocity is equivalent to a specification of an object's speed and direction of motion (e.g. 60 km/h to the north).

Answer:

Atomic mass of Sodium is 22.9897 u. Note that, each element may contain more isotopes, therefore this resulting atomic mass is calculated from naturally-occuring isotopes and their abundance. The unit of measure for mass is the atomic mass unit (amu). One atomic mass unit is equal to 1.66 x 10 -24 grams.

Answer:

It's called the shielding effect

Explanation:

It describes the decrease in attraction between an electron and the nucleus in any atom with more than one electron shell. (I hope this helps)

The attraction pull of the nucleus on its electron weakened by the shielding of the inner shell electron is called the shielding effect.

The shielding effect is the valence electrons are shielded from the attraction toward the nucleus of an atom. The shielding effect is the resistance offered by the inner shell electrons to the attraction of the valence electrons toward the nucleus.

This effect increases down the group in the periodic table as the atomic radii also increase and remains the same in the period. This effect is generated by the electrons present in the middle of the nucleus and valence electrons act as shields that repel those outer electrons.

Therefore, the effective nuclear charge acting on the valence electrons decreases. More shielding effect causes less electronegativity of an atom. The shielding effect describes how easily the electron can be removed from the atom making it more reactive.

We may suspend accounts that violate the Brainly Code of Conduct. Look for a follow-up email.  

The scenario that supports the "one gene-one enzyme" hypothesis of metabolic disease causation is Phenylketonuria (PKU). This disease (PKU) is caused by the failure to produce a functional variant of an enzyme.

Phenylketonuria (PKU) is a metabolic inherited disorder associated with a decreased metabolism of the amino acid phenylalanine.

PKU is caused by a mutation in the gene responsible for encoding a key enzyme needed to break down phenylalanine.

Untreated PKU may lead to diverse health problems which include brain damage, intellectual disability, seizures, mental disorders, etc.

A. W and X

Explanation:

Because W have just one valence electron, and X have 7, so it means that W will give its electron to X and that's the definition of an ionic bond

Answer:

Protons have a positive charge. Electrons have a negative charge. The charge on the proton and electron are exactly the same size but opposite. Since opposite charges attract, protons and electrons attract each other.

Answer:

b).   0.732

Explanation:

52g Na₂SO₄ x     1 mol Na₂SO₄       x      2 mol Na

                          -------------------------      --------------------  =  0.732 mol Na

                           142.04 g Na₂SO₄       1 mol Na₂SO₄

Atomic Mass Units

Na₂ = 22.99 x 2 = 45.98

S     = 32.06

O₄ = 16 x 4 = 64

Na₂SO₄ = 45.98 + 32.06 + 64 = 142.04

There are 2 moles of Na in 1 mole of Na₂SO₄

Answer:

0.5 mol of nitrogen gas.

Explanation:

18g of Magnesium in mol is equal to 18g/24 gmol-1 = 0.75 mol and 7g of nitrogen in mol is equal to 7g/14 gmol-1 = 0.5 mol,

Thus, When 18g of magnesium reacts with 7g of nitrogen it implies 0.75 mol of magnesium which reacts with 0.5 mol of nitrogen. :)

The number of moles of nitrogen gas which react with 18 g of magnesium

to form magnesium nitride compound is 0.5mol.

We need to find the number of mole for magnesium and nitrogen.

Mole= mass/molar mass

Magnesium= 18g/24gmol⁻¹ = 0.75mol of Mg

Nitrogen= 7g/14gmol⁻¹ = 0.5mol of N

This implies that when 18g of magnesium reacts with 7g of nitrogen it

means 0.75 mol of magnesium which reacts with 0.5 mol of nitrogen.
