Scale and measuring tape. 
To determine the mass and volume, you can find the density. The block will float if its density is less than that of water.

Answer:

Explanation:

To determine if the bock will float you need:

  • A scale to calcualte the weight of the block
  • A ruler or metric tape to measure the block and calculate its volume

The block has 3 dimmentions: lenght, wide and height, its volume is:

V=wide*lenght*height

Once calculated it and measured the  weight, you calculate the density:

\rho=\frac{m}{V}

If the density of the block is smaller than the density of water (arroung 1000 kg/m3) the block will float.

Give the value of the quantum number ℓ, if one exists, for a hydrogen atom whose orbital angular momentum has a magnitude of 6√(
MakcuM [25]

Answer:

For this angular momentum, no quantum number exist

Explanation:

From the question we are told that

   The magnitude of the angular momentum is  L  = 6\sqrt{\frac{h}{2 \pi} }

The generally formula for Orbital angular momentum is mathematically represented as

           L  = \sqrt{(l * (l + 1)) } *  \frac{h}{2 \pi}

Where l is the quantum number

now  

We can look at the given angular momentum in this form as

      L  = 6\sqrt{\frac{h}{2 \pi} }    =  \sqrt{36}  * \sqrt{\frac{h}{2 \pi}} }

comparing this equation to the generally equation for Orbital angular momentum

     We see that there is no quantum number that would satisfy this equation

EleoNora [17]

Answer:

C

Explanation:

It said in water it had a freezing point of 0.352oC. so right i the start i picked C because it sounds like it doesn't dissociates in water so that is my answer

Bridget is in science class. Her teacher gives her two unknown substances and asks her to determine their relative pH. She place
agasfer [191]
Litmus paper is often used to determine the range of pH of an aqueous solution. Litmus paper specifically contains 10-15 natural dyes, in the presence of acidic solution it turns red, it turns purple when the solution is neutral and blue when dealing with basic solutions. Red litmus paper stays red for a neutral and acidic solution but changes to blue in the presence of alkaline solutions. On the other hand, blue litmus paper turns red when a solution is acidic but stays blue for neutral and alkaline solutions. Since the paper turns purple in the presence of solution 1 we know that is neutral, meanwhile, since it turns blue for the second solution we know that solution II is a base correct answer is C
