What is required in order to determine whether or not an object moves?
AysviL [449]

Answer:

A reference point.

Explanation:

Reference point:

A reference point is a point which is used to determine weather the object is in motion or not. The moving object is compared with the reference point.

An object is in the state of motion when its distance is changed relative to the other object or reference point.

In order to determine weather an object is moving or not a point of reference is needed.

Without reference point displacement can not be measured

Sedaia [141]

Answer:

154 g

Explanation:

Step 1: Write the balanced decomposition equation

2 NaN₃(s) ⇒ 2 Na(s) + 3 N₂(g)

Step 2: Calculate the moles corresponding to 79.5 L of N₂ at STP

At STP, 1 mole of N₂ occupies 22.4 L.

79.5 L × 1 mol/22.4 L = 3.55 mol

Step 3: Calculate the number of moles of NaN₃ needed to form 3.55 moles of N₂

The molar ratio of NaN₃ to N₂ is 2:3. The moles of NaN₃ needed are 2/3 × 3.55 mol = 2.37 mol.

Step 4: Calculate the mass corresponding to 2.37 moles of NaN₃

The molar mass of NaN₃ is 65.01 g/mol.

2.37 mol × 65.01 g/mol = 154 g

Which five statements about hemoglobin and myoglobin structure are true? Each iron atom can form six coordination bonds. One of
Ulleksa [173]

Answer:

Here's what I get  

Explanation:

Each iron atom can form six coordination bonds. One of these bonds is formed between iron and oxygen.  

TRUE

By itself, heme is not a good oxygen carrier. It must be part of a larger protein to prevent oxidation of the iron atom.  

TRUE

Molecular oxygen binds irreversibly to Fe²⁺ in heme.  

False. It binds reversibly with heme.

Heme is composed of an organic protoporphyrin component and a metal atom.  

TRUE

Hemoglobin and myoglobin are heterotetramers.

False. Hemoglobin is a tetramer. Myoglobin a monomeric protein.

Both hemoglobin and myoglobin contain a prosthetic group called heme, which contains a central iron atom.

TRUE

Each hemoglobin molecule can bind four oxygen molecules; each myoglobin can bind only one oxygen molecule.

TRUE
