The required mass of calcium bromide is 35.98 grams.

<h3>What is molarity?</h3>

Molarity is any solution is define as the number of moles of solute present in per liter of solution as;

M = n/V, where

  • M = molarity = 4M
  • V = volume = 45mL = 0.045L

Moles will be calculated by using the above equation as:

n = (4)(0.045) = 0.18 mole

Relation between the mass and moles of any substance will be represented as:

n = W/M, where

  • W = given mass
  • M = molar mass

Mass of CaBr₂ = (0.18mol)(199.89g/mol) = 35.98g

Hence required mass of CaBr₂ is 35.98 grams.

A) what is hydrogen's carrying capacity? <br> b) what is lithium’s carrying capacity?
sladkih [1.3K]

Answer:

A)Hydrogen can be stored physically as either a gas or a liquid. Storage of hydrogen as a gas typically requires high-pressure tanks (350–700 bar [5,000–10,000 psi] tank pressure). Storage of hydrogen as a liquid requires cryogenic temperatures because the boiling point of hydrogen at one atmosphere pressure is −252.8°C.

B) carrying capacity of the lithium reserve will reach 10 million EV and 90 billion CE's RLBs for 50% recycling of lithium-containing waste, and 15 million EV and 150 billion CE's RLBs for 90% recycling.

Wet chemical system components typically are a storage tank or tanks, piping, nozzles, and a(an)?
MAVERICK [17]

Wet chemical system components typically are a storage tank or tanks, piping, nozzles, and an actuating mechanism.

<h3>Which parts make up an actuation mechanism?</h3>

The typical components of an actuation mechanism include a motor, transmission, control units, feedback, signaling, interlocking, and shutdown units. An electrical, hydraulic, or pneumatic drive is used to move a valve, shutter, or gate, which acts as an actuator to regulate the flow of fluids or gases.

<h3>What is the operation of the operator-dependent actuating mechanism?</h3>

When an automatic clutch is engaged, the control system 2 replaces the target-value signals coming over feeders 1 with the operator force signal if the operator uses the operator-dependent actuating mechanism.

Answer:

C

Explanation:

<em>The </em><em>specific</em><em> </em><em>heat </em><em>capacity</em><em>=</em><em>quantity</em><em> of</em><em> </em><em>heat</em><em> </em><em>in </em><em>joule/</em><em>mass×</em><em>c</em><em>h</em><em>a</em><em>n</em><em>g</em><em>e</em><em> </em><em>in </em><em>temperature</em>

<em>from </em><em>this </em><em>question</em><em> </em><em>the </em><em>quantity</em><em> of</em><em> </em><em>heat</em><em> </em><em>is </em><em>7</em><em>5</em><em>2</em><em>5</em><em>0</em><em>,</em><em>the </em><em>mass </em><em>is </em><em>2</em><em>0</em><em>0</em><em>0</em><em> </em><em>and </em><em>the </em><em>change </em><em>in </em><em>temperature</em><em> </em><em>is </em><em>5</em><em>0</em><em>-</em><em>3</em><em>0</em>
