6 0

Answer:

6.05 g

Explanation:

Use the density to convert the volume to a weight.

(5.00 mL) × (1.21 g/mL) = 6.05 g liquid plant food

You will need 6.05 g liquid plant food.

What type of central-atom orbital hybridization corresponds to each electron-group arrangement:
dimaraw [331]

The type of central-atom orbital hybridization corresponds to each electron-group arrangement

Linear

What is linear arrangement?

Linear molecules are molecules that are straight and have a bond angle of 180 degrees. These molecules are made up of a central atom that is bonded to two other atoms via single or double bonds (sometimes there can be triple bonds as well).

Furthermore, the central atom usually can have either 0 or 3 lone electron pairs (AX2 or AX2E3) in the AXE notation.

The geometry described by linear molecular geometry revolves around a central atom that is bonded to two other atoms (or ligands) at a bond angle of 180°.

When 2.50 mol of mg3n2 are allowed to react how many moles of h2o also react?
spin [16.1K]

Notice that in the equation given, there is 1 mol of Mg3N2 and 6 mol of H2O. Consequently, the question is requesting, if we took 2.5 mol of Mg3N2, how many mol of H2O would be essential to complete a similar reaction -- in quintessence, multiplying everything by 2.5: 

the solution would be: 6 * 2.5 = 15 mol

I need help with this one pls, ty! ASAP
LuckyWell [14K]

Answer:

Explanation:

1. A measure of how quickly velocity is changing is the acceleration

Acceleration is the rate of change of velocity with time. The rate at which a body is changing its velocity is known as the acceleration.

It is measured in the unit m/s²

2. Speed in a given direction is the velocity

Velocity is a vector quantity which measures the magnitude of motion in a specific direction. It is simply speed in a given direction.

When we say a motorcycle travels at the rate of 5m/s due east, we are describing the velocity of such body.

3. Force that resists moving one object against another is the friction

Friction is a force that opposes motion. It prevents a body from moving.

4. Measure of the pull of gravity on an object Weight

Weight is a measure of the amount of gravitational force on a body. It is mathematically expressed as;

         W = mg

W is the weight, m is the mass and g is the acceleration due to gravity

5 Tendency of an object to resist a change in motion is inertia

Inertia is the tendency of body to resist change in motion. It is the ability of a body to remain in a perpetual state of rest.

6 Size is the magnitude

2. 2AgNO3 + CaCl2 → 2AgCl + Ca(NO3)2
Slav-nsk [51]

Answer:

84.4g of AgCl

Explanation:

Based on the reaction:

2AgNO₃ + CaCl₂ → 2AgCl + Ca(NO₃)₂

<em>2 moles of AgNO₃ and 1 mole of CaCl₂ priduce 2 moles of AgCl and 1 mole of Ca(NO₃)₂</em>

<em />

100g of each reactant are:

AgNO₃: 100g × (1mol / 169.87g) = 0.589 moles

CaCl₂: 100g × (1mol / 110.98g) = 0.901 moles

For a complete reaction of 0.901 moles of CaCl₂ are necessaries 0.901×2 = <em>1.802 moles of AgNO₃. </em>As there are just 0.589moles, <em>AgNO₃ is limitng reactant</em>

<em></em>

0.589 moles of AgNO₃ produce:

0.589 moles × ( 2 moles AgCl / 2 moles AgNO₃) =

<em>0.589 moles of AgC</em>l. In mass:

0.589 moles of AgCl × (143.32g / mol) =<em> 84.4g of AgCl</em>
