Answer :
(a) The name of 
is, potassium dichromate.
(b) The name of 
is, lithium oxalate.
(c) The name of 
is, copper nitrate.
Explanation:
Ionic compound : It is a type of compound that is made up of the ions of the two different elements in which one element is a metal and another element is a non-metal.
(a)
The given compound is an ionic compound. It is made up of two different ions which are potassium ion 
and dichromate ion 
.
So, the name of is, potassium dichromate.
(b)
The given compound is an ionic compound. It is made up of two different ions which are lithium ion 
and oxalate ion 
.
So, the name of is, lithium oxalate.
(c)
The given compound is an ionic compound. It is made up of two different ions which are copper ion 
and nitrate ion 
.
So, the name of is, copper nitrate.
The answer to your question is liquid hydrogen
Answer:
See explanation below
Explanation:
To get this, we need to apply the general expression for half life decay:
N = N₀e(-λt) (1)
Where:
N and N₀ would be the final and innitial quantities, in this case, masses.
t: time required to decay
λ: factor related to half life
From the above expression we need λ and t. To get λ we use the following expression:
λ = t₁₂/ln2 (2)
And we have the value of half life, so, replacing we have:
λ = 8.04 / ln2 = 11.6
Now, we can replace in (1) and then, solve for t:
0.75 = 40 exp(-11.6t)
0.75 / 40 = exp(-11.6t)
ln(0.01875) = -11.6t
-3.9766 = -11.6t
t = -3.9766 / -11.6

t = 0.34 days</h2><h2>

Answer:b
Explanation:
From the question, the stoichiometry of the balanced reaction equation showed that 180gof glucose give 134.4L of CO2. Then we are given to find the volume of carbon IV oxide given off by 126g of glucose. This is done as shown in the image by relating what is given to the stoichiometry of the balanced reaction equation to obtain the answer as shown.
