What volume in ml of 0.500 M silver nitrate is required to completely react with 25.0 ml of 1.5 M calcium chloride?

Answers

Answer 1

Answer: First, the balanced chemical equation of the reaction must be written. This gives:

2 AgNO3 (aq) + CaCl2 (aq) --> 2 AgCl (s) + Ca(NO3)2 (aq)

This shows that for every mole of CaCl2, 2 moles of AgNO3 reacts (1:2 ratio). Given the volume and molarity of CaCl2, we can compute for the number of moles of CaCl2.

moles CaCl2 = 1.5M(25mL/1000) = 0.0375 moles

Now, we can also compute for the moles of AgNO3 using the balanced equation.

moles AgNO3 = 2(0.0375) = 0.075 moles

Using the moles and molarity of AgNO3, we can compute for the volume needed.

volume (mL)/1000 = 0.075/0.5 = 150 mL of silver nitrate solution is required.

Find the nth term of 2, 8, 18, 32, 50

Answers

From the series, 2, 8, 18, 32, 50,...

By observation and by trial and error.

The first term, n = 1    = 2*1*1 = 2

Second term, n =2,     = 2*2*2 = 8

Third, n =3,    = 2*3*3 = 18

Third term, n = 4, = 2*4*4 = 32

Fourth term, n =5, 2 * 5* 5 = 50

For nth term, 2 *n *n = 2n²

Therefore nth term = 2n²

If o is in the middle of l t, where exactly is it located? If l t =16 cm, what is l o and o t

Answers

Answer:

$LO = OT = 8cm$

Step-by-step explanation:

Given

LT = 16cm

Required

Determine LO and OT

First, we have:

$LO + OT = LT$

From the question, we understand that O is the middle of LT

This implies that LO = OT

Substitute OT for LO in the above formula

$OT + OT = LT$

$2OT = LT$

Divide both sides by 2

$OT = (1)/(2)LT$

Substitute 16cm for LT

$OT = (1)/(2) * 16cm$

$OT = 8cm$

Recall that LO = OT

So;

$LO = OT = 8cm$

Find the mode of the data set: 37, 42, 39, 44, 47, 38, 42, 45, 49, 35

Answers

The integer number 42 appears two times in a collection of the data. Then the mode of the data set will be 42.

What is the mode of the data?

Simply counting how several times each number looks in the data set can help you identify the mode, which is the integer that repeats the most frequently in the collected data. The figure with the largest total is the mode.

The data is given below.

37, 42, 39, 44, 47, 38, 42, 45, 49, 35

Arrange the data in ascending order, then we have

35, 37, 38, 39, 42, 42, 44, 45, 47, 49

The integer number 42 appears two times in a collection of the data. Then the mode of the data set will be 42.
