Which type of bond is found in many carbon-to-carbon bonds in canola oil, but very few carbon-to-carbon bonds in butter? a.)C–C
PtichkaEL [24]
B.)C=C is the right answer.
because h<span>aving more double bonds than single bonds decreases the melting point and, hence, the fluidity of the substance this is why butter is a solid but canola oil is a liquid at room temperature.</span>

If a 2,000-kilogram car accelerates at a rate of 3 meters
Nostrana [21]

Explanation:

Newton's second law of motion states that the acceleration of an object is dependant on the amount of force applied and the mass of the object itself, which is illustrated by the equation

                                                       F \ = \ ma,

where F is the force applied, m is the mass of the object and a is the acceleration.

Therefore,

                                                    F \ = \ (2000 \ \text{kg})(3 \ \text{m\,s}^{-2}) \\ \\ F \ = \ 6000 \ \text{N}

Hence, 6000 N of force is applied by the engine to the car.

How many milliliters of a 0.900% (m/v) normal saline solution can be prepared from 3.50 g of sodium chloride, NaCl
Bess [88]

Answer:

389 mL solution

Explanation:

Step 1: Given data

  • Concentration of the NaCl solution: 0.900% (m/v)
  • Mass of sodium chloride: 3.50 g
  • Volume of saline solution: ?

Step 2: Calculate the volume of saline solution

The concentration of the NaCl solution is 0.900% (m/v), that is, there are 0.900 g of NaCl every 100 mL of solution.

3.50 g NaCl × 100 mL solution/0.900 g NaCl = 389 mL solution
