Answer:
Lithium Fluoride
Explanation:
It should be lithium fluoride for sure :)
Answer:
D. They are different from the properties of carbon, oxygen, and hydrogen.
Step-by-step explanation:
Carbon, oxygen, and hydrogen are all <em>elements.
</em>
Sucrose is a <em>compound</em> containing carbon, oxygen, and hydrogen. Its properties are different from those of its elements.
For example, carbon is a <em>black solid,</em> while oxygen and hydrogen are <em>colourless gases</em>. Sucrose is a <em>white solid</em>.
<u>Answer:</u> The half life of the reaction is 1190.7 seconds
<u>Explanation:</u>
The equation used to calculate rate constant from given half life for first order kinetics:
where,
k = rate constant of the reaction = 
= half life of the reaction = ?
Putting values in above equation, we get:
Hence, the half life of the reaction is 1190.7 seconds
Grams of Ca(NO₃)₂ produced : 0.985 g
<h3>Further explanation</h3>
A reaction coefficient is a number in the chemical formula of a substance involved in the reaction equation. The reaction coefficient is useful for equalizing reagents and products.
Reaction
CaCl₂ + 2AgNO₃ → 2AgCl + Ca(NO₃)₂
MW AgNO₃ : 107.9+14+3.16=169.9
mol AgNO₃ :
mol ratio Ca(NO₃)₂ : AgNO₃ = 1 : 2, so mol Ca(NO₃)₂ :
MW Ca(NO₃)₂ : 40.1+2.14+6.16=164.1 g/mol
mass Ca(NO₃)₂ :
Answer:
A. More mass
C. Shorter distance between them
Explanation:
The two characteristics of a body experiencing greater gravitational force are that they have mass and a shorter distance between them.
This is conformity with Newton's law of universal gravitation.
The law states that "every object attracts one another with a force that is directly proportional to their masses and inversely proportional to the square of the distance between them".
This law implies that the more the mass of two bodies, the more the gravitational force of attraction. And that the shorter the square of the distance between them, the more the attraction.
