Answer:
1 hour
Explanation:
It takes 1 hour to drive 50 miles
Convert 74.2 g N₂ to moles. (N₂ molar mass ≈ 28.014 g/mol)
(74.2 g) (1/28.014 mol/g) ≈ 2.65 mol N₂
According to the balanced reaction, 1 mol N₂ and 3 mol H₂ get consumed together to produce 2 mol NH₃, which means we consume up to
3 (2.65 mol N₂) ≈ 7.95 mol H₂
That is, all the N₂ is consumed and we have an excess of about 6.05 mol H₂. We end up with
2 (2.65 mol N₂) ≈ 5.30 mol NH₃
or (with NH₃ molar mass ≈ 17.031 g/mol)
(5.30 mol) (17.031 g/mol) ≈ 90.3 g NH₃
The true statements after evaluating the expression based on principle of commutativity and associativity are :
A: x + y = y + x
B; (x × y) × z = x × (y × z)
D: (x + y) + z = x + (y + z)
We are given;
x = a + bi
y = c + di
z = f + gi
Now according to properties of algebra, we know that;
- Commutative property states that with addition and multiplication of numbers, you can change the order of the numbers in the problem and it will not affect the answer. For example; a + b = b + a
- The Associative property states that; a × ( b × c) = b × (a × c) = c × (b × a)
Looking at the options :
A) x + y = y + x ; This is true as it follows Commutative property of addition
B) (x × y) × z = x × (y × z) ; This is true as it follows the Associative property.
C) x - y = y - x ; this is false as it does not follow both properties.
D) (x + y) + z = x + (y + z) ; This is true as it follows the Commutative property.
E) (x – y) – z = x – (y – z) ; This is False as it does not follow any of the 2 properties.

1. Human rights are basic rights that belong to all of us simply because we are human. They embody key values in our society such as fairness, dignity, equality and respect. ... Most importantly, these rights give us power and enable us to speak up and to challenge poor treatment from a public authority.
2. On the support of victims of human rights violation, the law should clearly state and express the repercussions of violating human rights. The citizen on the other hand should be well versed with human rights and should report any violator of human rights to the relevant authorities for immediate action to be taken. The community can mobilize and make aware the people of their rights and also allow any victim of human rights violations to face the law and seek justice.
3.Undoubtedly, every Government’s foremost duty is to protect human rights. The Government has all the power and infrastructure such as the constitution, the judiciary, the police, etc. to do this.
The Government in India is taking all the measures to protect human rights. Wherever, any violation has happened, the Government has taken action and the offenders were brought to justice.
