An ice cube floats in warm water in a container placed outside on a hot, sunny day.
SCORPION-xisa [38]

Answer:

Firsthand association assigns energy throughout conduction. Radiation transpires when particles consume energy that progresses as a wave. The heat will run from the h2O to the ice continuously until the ice has absolutely melted so both elements have reached the same temperature.

If a solution has a [H+] of 9.3x10-11, what is the pH?
Rina8888 [55]

Answer:

<h2>10.03</h2>

Explanation:

The pH of a solution can be found by using the formula

pH = - log [ {H}^{+} ]

From the question we have

ph =  -  log(9.3 \times  {10}^{ - 11} )  \\  = 10.0315...

We have the final answer as

<h3>10.03</h3>

Hope this helps you

Which of the following is/are INCORRECT conversions in the metric system? Circle ALL that are false - there may be more than one
Artist 52 [7]

Answer:

(b) 50 mL = 0.50 L

Explanation:

Metric system is a measurement system that uses decimalized in all their factor, which mean every rank difference can be expressed as a factor of 10(deci=10). The decimalized number makes it easier to convert the unit, make the metric system easier to be learned and used.  

The Metric system will use a prefix to determine the factor, a kilo is 1000, mili is 1/1000, centi is 1/100, pico is 1/10^12.

(a) 1 km = 1000 m  

True, kilo is 1000

(b) 50 mL = 0.50 L

This option is false. mili is 1/1000, so 50/1000= 0.05 L

(c) 125 mm = 12.5 cm  

True, mili is 1/1000 while centi is 1/100.  

So 125mm will be: 125mm * 100mm/1000cm= 12.5cm

(d) 23 pm = 0.000  000  000  023 m

True, pico is 10^-12
