Answer:

An object at rest has zero velocity - and (in the absence of an unbalanced force) will remain with a zero velocity. Such an object will not change its state of motion (i.e., velocity) unless acted upon by an unbalanced force. An object in motion with a velocity of 2 m/s, East will (in the absence of an unbalanced force) remain in motion with a velocity of 2 m/s, East. Such an object will not change its state of motion (i.e., velocity) unless acted upon by an unbalanced force. Objects resist changes in their velocity

Explanation:

an object that is not changing its velocity is said to have an acceleration of 0 m/s/s. Thus, we could provide an alternative means of defining inertia

if 45.0 ml of 1.50 M Ca(OH)2 are needed to neutralize 25.0 ml of HI of unknown concentration, what is the molarity of the HI?

ipn [44]

Answer:

M of HI = 5.4 M.

Explanation:

We have the rule: at neutralization, the no. of millimoles of acid is equal to the no. of millimoles of the base.

(XMV) acid = (XMV) base.

where, X is the no. of (H) or (OH) reproducible in acid or base, respectively.

M is the molarity of the acid or base.

V is the volume of the acid or base.

(XMV) HI = (XMV) Ca(OH)₂.

For HI; X = 1, M = ??? M, V = 25.0 mL.

For Ca(OH)₂, X = 2, M = 1.5 M, V = 45.0 mL.

∴ M of HI = (XMV) Ca(OH)₂ / (XV) HI = (2)(1.5 M)(45.0 mL) / (1)(25.0 mL) = 5.4 M.

Which of these laboratory techniques is best to separate a solid from a liquid to recover the liquid? f chromatography g filteri

galina1969 [7]

Answer:
Filtering is best laboratory technique to separate a solid from a liquid to recover the liquid.

Explanation:
A solid particles present in liquids can be separated from liquid by utilizing a membrane having pores large enough to allow the liquid molecules to pass through and small enough to stop the solid particles from crossing.

Example:
Tea Filters are used to separate Tea from the grounds.

Kidney is an excellent example of Biological Filter.

Automobile catalytic Converters use a platinum callus to reduce air pollution by changing emissions such as carbon monoxide CO2

natka813 [3]

Answer:

14 mol O₂

Explanation:

The reaction between CO and O₂ is the following:

CO + O₂ → CO₂

We balance the equation with a coefficient 2 in CO and CO₂ to obtain the same number of O atoms:

2CO + O₂ → 2CO₂

As we can see from the balanced equation, 1 mol of O₂ is required to react with 2 moles of CO. Thus, the conversion factor is 1 mol of O₂/2 mol CO. We multiply the moles of CO by the conversion factor to calculate the moles of O₂ that are required:

28 mol CO x 1 mol of O₂/2 mol CO = 14 mol O₂

Carbon Dioxide in a 34 L container at a pressure of 387 mm Hg is transferred to a container with a pressure of 274 mm Hg. What i

AVprozaik [17]

Answer:

V2= 0.0796m3

Explanation:

We have that for a real gas the following relation is fulfilled:

PV / T = constant

To use this formula I need to pass the pressure of mmHg to KPa and the volume of L to m3, knowing that

1Kpa = 7.50062mmHg

1L = 0.001m3

So i can say

P1V1/T1 =P2V2/T2

V2= P1V1T2/P2T1

V2= 51.60KPa*0.034m3*350k/36.53KPa*211k

finally

V2= 0.0796m3
