When two distinct elements are chemically combined—i.e., chemical bonds form between their atoms—the result is called a chemical compound<span>. Most elements on Earth bond with other elements to form chemical compounds, such as sodium (Na) and Chloride (Cl), which combine to form table salt (NaCl).

Answer:
The answer is 3.87 J/g°C
Explanation:
Here is the equation we are going to use:
C= specfic heat in J/g°C
q = heat in joules (J)
m = mass in grams (g)
T = change in temperature
Here is what is given:
q = 849 J
m = 95.4 g
T = 48.0 - 25.0 = 23°C
Find:
Specific heat capacity in J/g
The first thing we are going to do is plug everything into the equation:
Then we are going to solve for C
Hope this helps!
Answer:
Explanation:
Arrhenius defined an acid as a substance that interacts with water to produce excess hydrogen ions in aqueous solution.
A base is a substance which interacts with water to yield excess hydroxide ions, in an aqueous solution according to Arrhenius.
Bronsted-Lowry theory defined an acid as a proton donor while a base is a proton acceptor.
Answer:1.34 ×10^-5
Explanation:
AgCl = (Ag+) (Cl-)
=(S)(S)
= S²
S stands for molar solubility
Ksp =S² = 1.80 × 10^ -10
S= √[1.80 × 10^ -10]
=1.34 × 10^-5
The correct answer is A. A <span> sample of sodium hydroxide (NaOH) has a mass of 160.0 g which is equal to 4 moles of NaOH. TO calculate this, we use the relation of the molar mass given.
160.0 g NaOh ( 1 mol NaOH / 40.0 g NaOH ) = 4.000 mol NaOH</span>
