Balanced equation : 2Na+I₂⇒2NaI
<h3>Further explanation
</h3>
Equalization of chemical reactions can be done using variables. Steps in equalizing the reaction equation:
• 1. gives a coefficient on substances involved in the equation of reaction such as a, b, or c, etc.
• 2. make an equation based on the similarity of the number of atoms where the number of atoms = coefficient × index (subscript) between reactant and product
• 3. Select the coefficient of the substance with the most complex chemical formula equal to 1
Reaction
Na+I₂⇒NaI
aNa+bI₂⇒NaI
Na, left=a, right=1⇒a=1
I, left=2b, right=1⇒2b=1⇒b=0.5
Equation becomes :
Na+0.5I₂⇒NaI x 2
2Na+I₂⇒2NaI
For this problem, assume ideal gas then we use the Combined Gas Law.
P₁V₁/T₁ + P₂V₂/T₂ = PV/T
where P, V and T are the total pressure, volume and temperature
Since temperature is kept constant, the equation is simplified to:
P₁V₁ + P₂V₂ = PV
(3.5 atm)(2L) + (2.6 atm)(1.5 L) = (P)(7 L)
Solving for P,
<em>P = 1.56 atm</em>
Answer:
Washing dishes in the dishwasher with detergent and hot water is a<u> Disinfecting</u> process.
<u>Explanation:</u>
There is a large number of micro-organisms present on the dishes which are yet to be washed. So when we wash them with detergent and hot water all the dishes get disinfected.
Disinfecting a dish makes it free from various germs present on it. When we disinfect a dish the germs or micro-organisms present are deactivated. This prevents their multiplication. Chemicals like Alcohol chlorine and hydrogen peroxide can be used as a disinfectant.
Answer:
69.6L
Explanation:
Using Charles law equation:
V1/T1 = V2/T2
Where;
V1 = initial volume (L)
V2 = final volume (L)
T1 = initial temperature (K)
T2 = final temperature (K)
According to this question, a gas takes up 50.0 L while at STP. A gas at STP will possess an initial temperature of 273K. Hence;
V1 = 50.0 L
V2 = ?
T1 = 273K
T2 = 380K
Using V1/T1 = V2/T2
50/273 = V2/380
CROSS MULTIPLY
380 × 50 = 273 × V2
19000 = 273V2
V2 = 19000 ÷ 273
V2 = 69.59
V2 = 69.6L
Answer:
The correct answer is no.
Explanation:
Tellurium is a chemical element denoted by Te and having atomic number 52. It is mildly toxic, brittle, silver-white, and rare metalloid. The element is chemically related to sulfur and selenium, all three of which are chalcogens.
Oxygen is a chemical element, that is, a substance, which comprises only one kind of atom. Its official chemical symbol is O and exhibits an atomic number 8, this signifies that an atom of oxygen possesses eight protons in its nucleus. In the given question, it is not likely that tellurium would replace for oxygen, as the two elements are highly unlike.
