Answer:

Explanation:

epulsion and attraction

Two charged objects will: repel each other if they have like charges (they are both positive or both negative) attract each other if they have opposite charges (one is positive and the other is negative)

Answer: If two electrically charged objects repel one another, that means, the two objects have the same electric charge. The opposite charges attracts each other while same charges repel each other. If there is one positive and one negative charge particle, they will attract each other. While If there are two positive charges or two negative...

<h3>Answer:</h3>

0.64 Moles of Propane

<h3>Explanation:</h3>

Data:

Moles of Carbon = 1.5 mol

Conversion factor = 7 mol C produces = 3 mol of Propane

Solution:

As we know,

7 moles of Carbon produces = 3 moles of Propane

Then,

1.5 moles of Carbon will produce = X moles of Propane

Solving for X,

X = (1.5 moles × 3 moles) ÷ 7 moles

X = 0.6428571 moles of Propane

Or rounded to two significant figures,

X = 0.64 Moles of Propane

Two isotopes of hydrogen fuse to form a neutron plus the larger element,A) beryllium.B) carbon.C) deuterium.D) helium.

Nezavi [6.7K]

Answer: D) helium.

Explanation:

Nuclear fission is a process which involves the conversion of a heavier nuclei into two or more small and stable nuclei along with the release of energy.

$_{92}^{235}\textrm{U}+_0^1\textrm{n}\rightarrow _{56}^{143}Ba+_{36}^{90}Kr+3_0^1\textrm{n}$

Nuclear fusion is a process which involves the conversion of two small nuclei to form a heavy nuclei along with release of energy.

Example: $_1^2\textrm{H}+_1^3\textrm{H}\rightarrow _2^4\textrm{He}+_0^1\textrm{n}+\text{energy}$

Thus when deuterium and tritium , the two isotopes of hydrogen are fused, a heavier nuclei helium is being formed from two smaller nuclei releasing a neutron.

Water-soluble vitamins: a. often result in toxicities b. are easily excreted in the urine c. are stored in body tissues to a lar

enyata [817]

Answer: Option (b) is the correct answer.

Explanation:

Vitamins which are soluble in water are known as water-soluble vitamins. And, vitamins which remain insoluble in water are known as water-insoluble vitamins.

Water-soluble vitamins are able to be easily excreted by the human body through urine. For example, vitamin C and vitamin B-complex are water soluble vitamins.

Thus, we can conclude that water-soluble vitamins are easily excreted in the urine.

For the reaction H₂O(g) + Cl₂O(g) → 2HClO(g), you know ΔS°rxn and S° of HClO(g) and of H₂O(g). Write an expression that can be u

expeople1 [14]

The expression for S°(Cl2O)(g) is given by ,

S°(Cl2O)(g) = 2×S°(HClO)(g) - S°(H2O)(g) - ΔS°rxn

Given ,

The balanced chemical equation is ,

H2O (g) + Cl2O (g) → 2HClO (g)

The general standard entropy of the reaction is given by ,

ΔS°rxn = sum of the S°(Product ) - sum of the S°(reactants )

ΔS°rxn = ΣmS°products - ΣnS°reactants

where , m and n are the stoichiometry coefficients of each product and reactants .

Thus , the standard entropy of the given reaction is given by ,

ΔS°rxn = 2×S° (HClO)(g) - [ S°(H2O)(g) + S°(Cl2O)(g) ]

ΔS°rxn = 2×S° (HClO)(g) - S°(H2O)(g) - S°(Cl2O)(g)

Thus the S°(Cl2O) is given by ,

S°(Cl2O)(g) = 2×S°(HClO)(g) - S°(H2O)(g) - ΔS°rxn

Hence the expression for the standard entropy of Cl2O (g) is given by ,

S°(Cl2O)(g) = 2×S°(HClO)(g) - S°(H2O)(g) - ΔS°rxn

<h3>What is a balance chemical reaction ?</h3>

A balanced chemical reaction is a type of reaction which include the reactants and products in same amount i.e. the no of mole on both side of the reaction is remains same or balanced .
