Answer: Is option C
Explanation: Earth has impact craters
Answer:
B) Co2 cuz in the diagram I see two similar atoms it might be of (oxygen) and the one atom of (carbon)
Answer is: d) NaHCO₃ - sodium hydrogen carbonate or s<span>odium bicarbonate.
It is because other salt are made in reaction between strong base and strong acid and </span>sodium hydrogen carbonate is made from strong base (sodium hydroxide) and weak acid (carbonic acid).
Sodium bicarbonate<span> is an aqueous solution is used for cases of </span><span>acidosis.</span>
The empirical formula is C₂H₆O.
We must calculate the <em>masses of C, H, and O</em> from the masses given.
<em>Mass of C</em> =38.20 g CO₂ × (12.01 g C/44.01 g CO₂) = 10.424 g C
<em>Mass of H</em> = 23.48 g H₂O × (2.016 g H/18.02 g H₂O) = 2.6268 g H
<em>Mass of O</em> = Mass of compound - Mass of C - Mass of H
= (20.00 – 10.424 – 2.6268) g = 6.9487 g
Now, we must <em>convert these masses to moles</em> and <em>find their ratios</em>.
From here on, I like to summarize the calculations in a table.
<u>Element</u> <u>Mass/g</u> <u>Moles</u> <u>Ratio</u> <u>Integers</u>
C 10.424 0.8680 1.999 2
H 2.6268 2.606 6.001 6
O 6.9487 0.4343 1 1
The empirical formula is C₂H₆O.
D.
A parent with type A B blood can ever have a child child with type O blood.
Explanation:
An offspring gets an allele for blood type from every parent. Therefore unless both parents have blood type O the offspring cannot have blood type O.
A person with blood group O means they do not blood group antigen on their red blood cells. They cannot pass the antigens to their offspring. A person with AB means they have both antigens for A & B blood groups and can pass either to any of the offspring they have.
The passing down of the blood group alleles follow the Mendelian principles of independent assortment.
