Which city had the highest temperature is Death Valley, California on July 10, 1913

<h3>Explanation: </h3>

Temperature expresses hot and cold, and it measured with a thermometer. On the afternoon July 10, 1913, the US Weather Bureau recorded a high temperature of 134 °F (56.7 °C) at Furnace Creek in Death Valley. This temperature stands as the highest ambient air temperature recorded at the surface of the Earth, ever.

Death Valley is a desert valley in Eastern California. It is located in the northern Mojave Desert bordering the Great Basin Desert. Death Valley is one of the hottest places in the world along with deserts in the Middle East. Name "Death Valley" was given because its forbidding name by a group of pioneers lost here in the winter of 1849-1850

How many moles of oxygen are required to produce 37.15 g CO2?

denpristay [2]

Carbon = 12.010. Oxygen = 15.999 x 2 15.999 x 2 = 31.998 + 12.010 = 44.008 \frac{37.15 grams * 1 mole CO2}{44.008 grams}

I need help with my chemistry homework please & thank u

lisov135 [29]

Answer:

6) solid- dots close together

liquid- a little bit farther apart than solid

gas- far apart

7) the movement of anything from a higher area of concentration to an area of lower concentration.

8) B. evaporation

9) The solute is the thing being dissolved, the solvent is the thing dissolving it, and the solution is the product of the solute and solvent.

10) D. regular brewed coffee

Under which conditions (in terms of kinetic energy) does boiling occur? How is the kinetic energy in the liquid increased?

Simora [160]

Explanation:

Boiling is defined as a process in which vapor pressure of a liquid substance becomes equal to the atmospheric pressure.

During this change liquid and vapors remain in equilibrium and the equation for this change is as follows.

$X(l) \rightleftharpoons X(g)$

Therefore, when boiling takes place then average kinetic energy of particles in liquid phase equals to the average kinetic energy of particles in vapor phase.

Hence, we can increase the kinetic energy of particles in liquid phase by increasing the temperature because kinetic energy is directly proportional to temperature as follows.

K.E = $\frac{3}{2}kT$

Okay so this is half math half chemistry...

AleksandrR [38]

So you need to find the volume in L? If so:
Convert the mass of Lithium Bromide into moles by dividing the 100 grams by the molar mass of LiBr, taken from the periodic table
In a solution, moles = (concentration in mole/L) x (volume in L)
We know the moles, we have the concentration in mole/L, now find the volume in L, and you should get 0.288. Plz do the math and check for yourself

Someone please help me!!!!

Double replacement :

2Na₃PO₄+3CaCl₂⇒6NaCl + Ca₃(PO₄)₂

<h3>Further explanation</h3>

1. A single replacement reaction is a chemical reaction in which one element replaces the other elements of a compound to produce new elements and compounds

2. Double-Replacement reactions. Happens if there is an ion exchange between two ion compounds in the reactant to form two new ion compounds in the product

3. Combination/syntesis : 2 or more reactants combine to form a new compound

4. Decomposition : the reactant is decomposed into 2/more products

If we look at the reaction options available, all of them can be included in the double replacement reaction, but we only choose the reaction from Sodium phosphate and Calcium chloride which leads to options: C because it is balanced (from the number of atoms in the same reactant and product) and is in accordance with the chemical formula of each compound (both products and reactants)
