Answer:
1.) NH₄
Explanation:
Atoms are depicted by letters in chemical formulas. Nitrogen atoms are represented by the letter "N" and hydrogen atoms are represented by the letter "H". One letter indicates one atom.
As such, if there is 1 nitrogen atom and 4 hydrogen atoms in ammonium, the chemical formula is NH₄.
D = m / V
D = 360 / 7.5
D = 48 g/cm³
Answer D

Bitter taste, high pH, and caustic Bitter are the characteristics of base.
<h3>What are the characteristics of base?</h3>
Bases have bitter taste, soapy feel, turn red litmus paper blue. Bases are substances that contain metal oxides or hydroxides. Its pH is higher than 7 up to 14.
So we can conclude that bitter taste, high pH, and caustic Bitter are the characteristics of base.

Answer:
Q = 2.60 • 
J
Explanation:
Our specific heat capacity equation is:
Q = mC∆T
Q is the energy in joules.
m is the mass of the substance.
∆T is the temperature chance.
Let's plug in what we know.
- We have 76.0 g of octane
- The specific heat capacity of octane is 2.22 J/(g•K)
- The temperature increases from 10.6º to 26.0º (a 15.4º increase)
Q = 76.0(2.22)(15.4)
Multiply.
Q = 2598.288
We want three significant figures.
Q = 2.60 •
or
Q = 2590 J
