Answer:
See explanation
Explanation:
A word equation tries to depict a chemical reaction in words. Letters rather than only chemical formulas are used to show the reaction equation.
Now we want to write a word equation that shows the reaction of sodium hydroxide solution and aluminium sulphate solution:
Alumunium sulphate + sodium hydroxide ------>Aluminium hydroxide + sodium sulphate
Answer:
I think it's c). <em>Radiation. </em>I wasn't really sure so I done a go o.gle search and that is what I found. If you want further information, here it is: On Earth, heat travels by conduction, convection and radiation. In space, conduction and convection are almost entirely non-existent. Radiation is the primary way that heat travels in space. Pls let me know if this helps. Mark as brainliest if u can.

Answer:
7 cm
Explanation:
If the following digit is greater than or equal to 5, the decimal place is rounded up (moved up to the next number); if the following digit is less than 5, the decimal place stays the same.
4.6 + 2.35 = 6.95 cm
However, as stated in your question, cm is only being measured to the nearest 0.1 centimeters in your question.
So, you would round the digit 9 up by 1, meaning you would round it to 10. However, there are only nine digits available in our base-10 counting system, so you carry the value over,
6.95 cm could be rounded to '6. 100 cm', which is 7 cm.
Answer:
An endothermic process is any process with an increase in the enthalpy H (or internal energy U) of the system. In such a process, a closed system usually absorbs thermal energy from its surroundings, which is heat transfer into the system.
Mass is measured by using a balance
