b. a covalent compound because it has a low boiling point
c.an ionic compound because it has a low melting point
d.a covalent compound because it has a low melting point
Answer: A solid compound in a sealed container is a covalent compound because it has a low melting point.
Explanation:
Ionic compounds have strong electrostatic forces which are strong in nature and cannot be broken down at low temperature.
Whereas covalent compounds have Vanderwaal forces which are weak in nature. Therefore, covalent compounds melts at low temperature.
Thus, it can be concluded that a solid compound in a sealed container is a covalent compound because it has a low melting point.
Answer: The answer is d
Explanation:
If you’ve ever smoked a joint or eaten a pot-laced brownie, you’re hardly alone: More than 1 in 3 people in America have tried marijuanaat one point in their lives.
Though occasional use isn’t usually harmful, pot can affect your body and mind any time it gets into your system. Here’s what you need to know.
Physical EffectsMarijuana comes from the hemp plant Cannabis sativa. It has an active ingredient called THC that makes you feel high. THC and other compounds in marijuana can also affect the way your body works.
b. False
The effect of warm tropical waters meeting with cool air is hurricane.
A hurricane is formed when warm tropical water meet with air that is cool and humid. This creates a zone of pressure over the warm water causing the air to rotate.
Hence, the effect of warm tropical waters meeting with cool air is hurricane.

Answer:
$182 is the value of the gold in the coin
Explanation:
Diameter is 2r, the ratio of the coin is = 1.62cm / 2 = 0.81cm
Following the formula of the volume of the coin:
V = π r² h
V = π*(0.81cm)²*0.085cm
V = 0.172cm³ = mL
As the density of the gold is 19.32g/mL, the mass of 0.1752mL of gold is:
0.1752mL * (19.32g / mL) =
3.385g is the mass of the coin
As the price of the gold is $53.90 / g, the value of the gold in the coin is:
3.385g * ($53.90 / g) =
To find the value of the gold in the coin, calculate its volume using the formula for the volume of a cylinder. The value of gold in the coin is $185.37.
To calculate the value of gold in the coin, we need to find its volume first using the formula for volume of a cylinder:
The radius (r) of the coin is half its diameter, so it is 0.81 cm. The height (h) is 0.085 cm. Plugging in these values, we can find the volume of the coin. Next, we calculate the mass of the gold in the coin using its density and the volume we just calculated. Finally, we multiply the mass by the price per gram of gold to find the value of the gold in the coin.
The volume of the coin is:
= 0.178 cm3.
The mass of the gold is:
m = density x volume
= 19.32 x 0.178
= 3.443 g.
The value of the gold in the coin is the value as -
= mass x price per gram
= 3.443 g x $53.90/g
= $185.37.
