You should choose the compound with the high melting point. Ionic compounds have high melting points because the electrostatic interactions are an extremely strong.

You are watching: You are given the melting points of three unknown substances

Hope this help you!

To heat 2.0 together of tea (d = 1.01 g/ml; sp. Warmth = a cook places a 500 g block of stone at a temperature that 200f right into the teapot. A
Volume of tea V = 2.0L = 2000 mL density d = 1.01 g/ mL mass the tea m = V * d = 2000mL * 1.01g/mL = 2020 gWhen us assume the the tea was initially at 72, the last temperature of the tea in F is 91. The ptcouncil.net in this inquiry is B. 91

ptcouncil.net: 7200 m

Explanation: The solution is, first convert 15 minute to seconds.

15 mins x 60 s / 1 min = 900 s

Use the formula for speed which is v= d/t climate derive for d.

d = vt

= 8 m/s ( 900s)

= 7200 m



Carousel conveyors are supplied for storage and order choose for little parts. The conveyorsrotate clockwise or counterclockwise, as

ptcouncil.net:

the variety of carousel conveyors that an operator can operate without any type of idle time is 5

Explanation:

Given the data in the question;

first us express the equation for variety of carousel conveyors that have the right to be activate by one operator;

n" =

*

where a is the concurrent task time ( 0.25 minute )

b is the elevation operator task time

t is the independent device activity time( 1 )

Now independent task time is zero as the operator is no performing any type of inspection or packaging tasks.

So time taken for the operator come retrieve the finished item in ~ the finish of the procedure is the concurrent task and independent device activity time, the conveyor rotation time of every item

so

we substitute

0.25min because that a, 1 for t and 0min for b

n" =

*

n" = 1.25 min / 0.25

n" - 5

Therefore, the number of carousel conveyors that an operator deserve to operate without any kind of idle time is 5

White irradiate (light containing every frequencies of light in the clearly shows spectrum) passes through a diffraction grating v 1300 l
lara31 <8.8K>

ptcouncil.net:

The distance between the 1st order blue fringe and also the first order red fringe is 6.5 cm.

See more: ( A Formula That Performs A Calculation S With Formulas, Access Chapter 5 Flashcards

Explanation:

Given that,

Diffraction lattice =1300 lines/cm

Distance of screen = 2 m

Order number = 1

We must calculate the distance between the first order blue fringe and also the first order red fringe

Using formula that distance

For an initial order red fringe

*

*

*

*

*

For very first order blue fringe

*

*

We must calculate the distance in between blue fringe and also red fringe

*

*

*

Hence, The distance in between the 1st order blue fringe and also the first order red fringe is 6.5 cm.
