How many mg of metallic ions are in 1.0 mL of 0.10 M LINO3
Answer:
0.6941 mg
Explanation:
First we calculate how many LiNO₃ moles there are, using the given concentration and volume:
1.0 mL * 0.10 M = 0.10 mmol LiNO₃As 1 mol of LiNO₃ contains 1 mol of Li, in the problem solution there are 0.10 mmol of Li (the only metallic ion present).
Now we convert Li milimoles into miligrams, using its atomic mass:
0.10 mmol Li * 6.941 mg/mmol = 0.6941 mgA basketball has a mass of 0.625 kg. Most basketball hoops are at a height of 3 m above the ground. What is the gravitational potential energy of a basketball just before it goes through the hoop?

What happens when water interacts with rock formations
Answer: It will erode or dissolve.
Explanation: Erosion is the process when water makes contact with rock. If water makes contact with rock, it will dissolve, partially or completely. Also, if the rock has cracks in it, the water will fill in the cracks, and when it turns winter, the rock is crumble, due because the water will turn into ice when it's winter.
When water interacts with rock formations it results into weathering.
What is Weathering?Weathering is the breaking down or dissolving of rocks and minerals on Earths surface. Once a rock has been broken down, a process called erosion transports the bits of rock and minerals away.
Weathering has no moving agent of transport, whereas in Erosion the rock and upper layer soil particles are worn away and moved elsewhere by water, wind, etc.
Rock exchange usually involves chemical deterioration in which the mineral composition in the rock is altered, rearranged or redistributed. Rock minerals are subjected to solution, carbonation, hydration and oxidation with circulating water.
Therefore, when water interacts with rock formations it results into weathering.

A glass sphere is filled to full volume with a gas. The pressure of the gas inside the sphere is 30.0 atm, and the temperature is 30.0°C. The sphere is taken outside on a cold day. The temperature of the gas decreases to 10.0°C. What is the new pressure of the gas? Assume that the volume is constant.
Answer:
28atm
Explanation:
Using Gay lussac's law equation as follows:
P1/T1 = P2/T2
Where;
P1 = initial pressure (atm)
T1 = initial temperature (K)
P2 = final pressure (atm)
T2 = final temperature (K)
Based on the information provided in this question;
P1 = 30.0 atm, T1 = 30.0°C, P2 = ?, T2 = 10.0°C
NOTE: Absolute temperature i.e. Kelvin is required for this law
T1 = 30°C + 273K = 303K
T2 = 10°C + 273K = 283K
Using P1/T1 = P2/T2
30/303 = P2/283
Cross multiply
P2 × 303 = 30 × 283
303P2 = 8490
P2 = 8490/303
P2 = 28.02
New pressure of the gas = 28atm

Select the boxes next to three properties that are typical of metals ??PLS I Will GIVE BRAINLY TO FIRST
Answer:
option b is correct
Explanation:
Metals are particularly good conductors of heat because their particles are very closely packed so the vibrations are passed on very quickly. They also contain large numbers of free electrons. These drift slowly through the structure, giving metals their strength and other properties. As the metal is heated, the free electrons closest to the heat source are heated. This makes them move faster and they travel through the metal, colliding with both atoms and other electrons. This naturally makes these vibrate faster (or move through the metal faster in the case of collisions with other free electrons). Thus, the heat is passed quickly through the metal.

1.) What is the maximum number of grams of liquid water at 10C that can be heated to
30C by the addition of 84 joules of heat?
Answer:
m = 1 gram
Explanation:
Given that,
Heat, Q = 84 J
The temperature increases from 10°C to 30°C.
We need to find maximum number of grams of liquid water. We know that the heat required is given by :
[tex]Q=mc\Delta T[/tex]
c is specific heat of water, c = 4,200 J/kg°C
Use the above formula to find m. So,
[tex]m=\dfrac{Q}{c\Delta T}\\\\m=\dfrac{84}{4,200\times (30-10)}\\\\m=0.001\ kg[/tex]
or
m = 1 gram
So, the required mass is 1 gram.

In a fractionating column, what process is caused by heating?
Answer:
During the fractional distillation of crude oil: heated crude oil enters a tall fractionating column , which is hot at the bottom and gets cooler towards the top. vapours from the oil rise through the column. vapours condense when they become cool enough.
Hope it helps you :)
The fractionating column's crystal clear glass beads provide such a vast surface area for heated vapors to cool and condensed continuously.
The fractionating column is inserted into the mouth of the distillation flask, which contains the saturated solution to be separated.
Heated crude oil is pumped into a tall fractionating column that is heated at the bottom and cools as it rises.
The oil fumes ascend through the column. When vapors cool down sufficiently, they condense. Various heights are used to lead liquids out of the columns.

anyone know how to do this?
Answer:
3.26×10⁵ L
Explanation:
From the question given above, the following data were obtained:
Initial volume (V₁) = 3.5×10⁵ L
Initial temperature (T₁) = 27 °C
Initial pressure (P₁) = 101 KPa
Final temperature (T₂) = –10 °C
Final pressure (P₂) = 95 KPa
Final volume (V₂) =?
Next, we shall convert celsius temperature to Kelvin temperature. This can be obtained as follow:
T(K) = T(ºC) + 273
Initial temperature (T₁) = 27 °C
Initial temperature (T₁) = 27 °C + 273
Initial temperature (T₁) = 300 K
Final temperature (T₂) = –10 °C
Final temperature (T₂) = –10 °C + 273
Final temperature (T₂) = 263 K
Finally, we shall determine the new volume of the tank. This can be obtained as follow:
Initial volume (V₁) = 3.5×10⁵ L
Initial temperature (T₁) = 300 K
Initial pressure (P₁) = 101 KPa
Final temperature (T₂) = 263 K
Final pressure (P₂) = 95 KPa
Final volume (V₂) =?
P₁V₁ / T₁ = P₂V₂ / T₂
101 × 3.5×10⁵ / 300 = 95 × V₂ / 263
117833.333 = 95 × V₂ / 263
Cross multiply
95 × V₂ = 117833.333 × 263
95 × V₂ = 30990166.6
Divide both side by 95
V₂ = 30990166.6 / 95
V₂ = 3.26×10⁵ L
Thus, the new volume of the tank is 3.26×10⁵ L

82.7% C and 17.3% H
89.4% C and 10.6% H
Answer:82.7% C and 17.3% H
Explanation:
C4 = 12.0107g/mol x 4 = 48.0428 g/mol
H10 = 1.00794 g/mol x 10 = 10.0794 g/mol
Molar Mass of Butane, C4H10 = 48.0428 g/mol + 10.0794 g/mol= 58.1222 g/mol
percent composition of Carbon is = ( mass of carbon contained in butane / molar mass of Butane) x 100
=(48.0428 /58.1222) x 100% = 0.8265 x 100
=82.65% =82.7% of Carbon.
Percent composition of Hydrogen = (mass of Hydrogen contained in Butane / molar mass of Butane )x 100

A) A positive linear relationship
B) A negative linear relationship
C) A negative but not linear relationship
D) A positive but not linear relationship
Answer:
D) A positive but not linear relationship
Explanation:
This comes from the equation Ek=1/2mv^2
Where Ek is Kinetic Energy, m is mass, and v is the speed (or velocity).
As we can see in the equation, the relation is not linear but quadratic and it is positive.
Answer:
D) A positive but not linear relationship
Explanation:
Speed is equal to distance divided by time. ... Therefore, the kinetic energy of an object is proportional to the square of its velocity (speed). In other words, If there is a twofold increase in speed, the kinetic energy will increase by a factor of four.
