Anna71 [15]2 years ago
7 0

Answer:

150.0 mL.

Explanation:

  • It is known that the no. of millimoles of HNO₃ before dilution = the no. of millimoles of HNO₃ after dilution.

∵ (MV) before dilution = (MV) after dilution.

<em>∴ V before dilution = (MV) after dilution / M before dilution</em> = (0.15 M)(500.0 mL)/(0.50 M) = <em>150.0 mL.</em>

16. As he developed his periodic table, Mendeleev grouped the elements lithium,
Aleonysh [2.5K]

Answer:

the reactivity and the valence electrons

Explanation:

the reactivity of the elements would have played a significant role in why such elements were grouped together. the number of valence electrons dictates how reactive an element is - the less valence electrons the more reactive it is. the column, group 1 in which these elements are put together in, show that each of the elements have 1 valence electrons and are therefore reactive.

you can go on to further explain what valence electrons are, explain what the group numbers are associated with the valence electrons and how valence electrons effect reactivity. further this, talk about how the three elements have the same number of valence electrons and therefore were grouped together

If you had continued following the water molecule in the Water Cycle Activity, what step do you predict would have occurred next
tamaranim1 [39]

Answer:option D is the correct answer, precipitation and it is because water is being released from the cloud into the earth.

Explanation:

PRECIPITATION is the process by which water condenses in the atmosphere. Precipitation can occur in form of snow,fog, dew,rain etc.

Atmospheric water is found in clouds and water vapor. Gradually and systematically the entire atmosphere rotates around the planet. When weather is being formed one of the most common results is precipitation.

In the water molecule activity here, precipitation will occur because water is being released from the atmosphere into the earth.

How does heat transfer through conduction
Alexeev081 [22]

Answer: Conduction is the process by which heat energy is transmitted through collisions between neighboring atoms or molecules. ... The fire's heat causes molecules in the pan to vibrate faster, making it hotter. These vibrating molecules collide with their neighboring molecules, making them also vibrate faster.
