What atom has the larger atomic radius Ca or Ni ?

Consider the following reaction: 2{\rm{ N}}_2 {\rm{O(}}g)\; \rightarrow \;2{\rm{ N}}_2 (g)\; + \;{\rm{O}}_2 (g)

fredd [130]

Answer:

a. 5.9 × 10⁻³ M/s

b. 0.012 M/s

Explanation:

Let's consider the following reaction.

2 N₂O(g) → 2 N₂(g) + O₂(g)

a.

Time (t): 12.0 s

Δn(O₂): 1.7 × 10⁻² mol

Volume (V): 0.240 L

We can find the average rate of the reaction over this time interval using the following expression.

r = Δn(O₂) / V × t

r = 1.7 × 10⁻² mol / 0.240 L × 12.0 s

r = 5.9 × 10⁻³ M/s

b. The molar ratio of N₂O to O₂ is 2:1. The rate of change of N₂O is:

5.9 × 10⁻³ mol O₂/L.s × (2 mol N₂O/1 mol O₂) = 0.012 M/s

When water vapor changes to a liquid what is it called

Mademuasel [1]

Answer:

$hello \: your \: answer \: is \: here.$

Explanation:

<h2>Condensation is the change of water from its gaseous form (water vapor) into liquid water. Condensation generally occurs in the atmosphere when warm air rises, cools and looses its capacity to hold water vapor. As a result, excess water vapor condenses to form cloud droplets.</h2>

What is the mass of 4.42 cm3 of platinum? The density of platinum is 22.5 g/cm3. (Sig Fig rules + units)

fgiga [73]

Answer: 99.45 g

Explanation: we have 22.5 g of Platinum in every 1cm3 of Platinum so if we take 4.42 cm3 of Platinum we will have 4.42 × 22.5 g = 99.45 g of Platinum

In an acid-base titration, a base or acid is gradually added to the other until they have completely neutralized each other. Sin

Xelga [282]

Answer:

1/10 or 0.1

Explanation:

Quantities at which equivalence can be obtained are:

95, 96, 97, 98, 99, 100, 101, 102, 103, 104

Number of quantities = N = 10

Probability that the equivalency is obtained exactly at 100 mL can be calculated as follows:

P(X = 100) = (Number of favourable outcomes) / (Total Number of Outcomes)

P(X = 100) = 1/10

P(X = 100) = 0.1
